I met him fifteen years ago. I was told there was nothing left. No reason, no conscience, no understanding and even the most rudimentary sense of life or death, of good or evil, right or wrong. I met this six-year-old child with this blank, pale, emotionless face, and the blackest eyes... the Devil's eyes. I spent eight years trying to reach him, and then another seven trying to keep him locked up, because I realized that what was living behind that boy's eyes was purely and simply...evil.
~ Loomis to Sheriff Brackett.
It's time, Michael.
~ Dr. Loomis' last words to Michael Myers in Halloween II before his sacrifice.

Dr. Samuel J. Loomis is the deuteragonist of the Halloween franchise.

He appears as the deuteragonist of Halloween (1978), Halloween 4: The Return of Michael Myers, Halloween 5: The Revenge of Michael Myers, Halloween: The Curse of Michael Myers, Halloween (2007) and Halloween II (2009), the main protagonist of Halloween II (1981) and a posthumous protagonist in Halloween H20: Twenty Years Later, Halloween: Resurrection, Halloween (2018) and Halloween Kills. He is the arch nemesis and former psychiatrist of masked serial killer Michael Myers.

Loomis' history is complicated by the fact that the series follows several conflicting continuities. Halloween H20: Twenty Years Later and Resurrection ignore the events of Halloween 4, 5, and 6, splitting the series into two separate timelines both originating from the original film and its sequel. The 2007 remake reboots the series continuity altogether, starting the timeline afresh.

He was portrayed by the late Donald Pleasance in the original and Malcolm McDowell in the remake.


Halloween (1978)

Meeting Michael Myers

In 1963, Loomis, then a child psychiatrist working at Shady Groves Sanitarium, met six-year-old Michael Myers, who had been institutionalized for murdering his older sister Judith the previous Halloween. Michael was a blank, emotionless slate to Loomis, never speaking and barely even moving. Loomis recognized that the boy was seriously disturbed, and knew that special treatment would be required if he were to ever help him. After eight fruitless years of trying to reach Michael, however, Loomis realized that he was not insane, but evil.

Loomis pleaded with the hospital administrators to transfer Michael to a maximum-security prison, but they brushed off Loomis' request, dismissing Michael as "a catatonic" who did not pose a threat to anyone. Loomis insisted to be taken seriously because he was convinced Michael's apparent catatonia was an ingenious cover for his true nature, but he was again ignored. Loomis spent the next eight years making sure that Michael would never be released.

Michael's escape

On October 30, 1978, Loomis is accompanied by his friend and medical assistant Nurse Marion Chambers; they are charged with transferring Michael back to his home county for a hearing determining whether Michael would be released or institutionalized indefinitely; Loomis plans to advocate for the latter.

When the pair reaches the gates of the sanitarium, they discover that many patients are wandering around the grounds. Loomis goes to the main gate to telephone the hospital, but Michael appears and nearly attacks Marion while she is waiting in the car.

Michael then escapes from the Illinois state hospital, hijacking the car meant for his court date transfer. His plan is to return to his hometown of Haddonfield and kill as many people as possible. Driving the 150 miles to his destination, he arrives in Haddonfield in time for Halloween.

Loomis is on Michael's trail for the entire date of October 31. While en route to Haddonfield, Loomis stops along a rural highway in west central Illinois to call Haddonfield authorities. He has every reason to believe Michael will return home, so he urges that the police watch out for him.

When the psychiatrist finally arrives in Michael's hometown, he seeks the help of Haddonfield Memorial Cemetery's grave keeper. The pair discovers that the headstone of Judith Myers had been removed and is missing. This clue is enough to assure Loomis that his patient is physically in the city.

That afternoon, Loomis enlists the help of Haddonfield's sheriff, Leigh Brackett. The pair later travels to the former Myers residence at 45 Lampkin Lane. Loomis is curious to know if Michael had returned to his childhood home. When they inspect the house, they find the front door broken and a dead dog, convincing Loomis that Michael has indeed been there. Loomis explains Michael's history and pathology to Brackett, and insists that Haddonfield is not safe while Michael is free.

While Michael stalks Laurie Strode, killing several of her friends, Loomis waits and watches over the house, believing that Michael will return home. When he discovers the stolen car, he begins combing the streets, where he finds the two children that Laurie is babysitting running, terrified, from their house. Loomis investigates and sees Michael attacking Laurie.

When Laurie pulls Michael's mask off, he stops to re-apply it, giving Loomis the opportunity to shoot his former patient six times, knocking him to and off the balcony of the two-story house. Laurie asks Loomis if her attacker was "the bogeyman"; Loomis replies, "As a matter of fact, it was." Loomis walks over to the balcony and looks down to see that Michael is gone.

Halloween II (1981)

Laurie is taken to Haddonfield Memorial Hospital while Sheriff Brackett accompanies Loomis in his search for Michael. While searching, Loomis believes that he has found Michael who quickly runs away from the police only to get hit in a car crash.

Everyone believes that Michael is dead, but Loomis is not sure. Just then, deputy Gary Hunt arrives and tells Brackett that his daughter Annie has been murdered. They arrive at the Wallace home where Brackett has to identify his daughter and then leaves his duties to Hunt as he has to go tell his wife the news. Before he leaves, he blames Loomis for unleashing Michael upon the town.

Loomis and Hunt go to the coroner's office, where they try to identify the body that was burned. It turns out that it was in fact not Michael, but teenager Bennett Tramer. Loomis and Hunt then head towards Haddonfield Elementary School, where they see Michael has written the word "Samhain" on the chalkboard in blood.

Loomis is ordered to leave Haddonfield by the state government so as to not create panic. Chambers has arrived to take Loomis back home. She also reveals to him one shocking fact: Michael is Laurie's older brother. With this newfound knowledge, Loomis realizes Michael returned to Haddonfield to kill his younger sister. Panicked, Loomis hijacks the police car that is taking him away from Haddonfield and heads for the hospital to stop Michael.

Loomis races to Laurie's aid and, once again, shoots Michael several times, which does not stop him. Loomis and Laurie run to a nearby operating room, where Loomis attempts to shoot Michael in the head. Not realizing his gun is empty, Loomis fires an empty chamber, and Michael stabs him in his stomach. Nevertheless, Loomis recovers, and he and Laurie fill the room with oxygen and ether. As Laurie runs away, Loomis stays behind. He tells Michael that "it's time" and proceeds to blow himself up with Michael.

Halloween 4: The Revenge of Michael Myers

The fourth film in the franchise reveals that Loomis survived the explosion, but suffered severe third-degree burns and a pronounced limp. Michael also survived the explosion, but fell into a coma.

In 1980, Laurie Strode had a daughter named Jamie Lloyd before apparently dying in a car accident. On October 30, 1988, Michael awakens from his coma upon hearing that that he has a niece. He kills his doctors and escapes, determined to go back to Haddonfield. Loomis unsuccessfully attempts to alert the police that Michael is now free, and pursues Michael himself.

Arriving at a filling station, Loomis encounters Michael and attempts to reason with him, offering to sacrifice his own life to Michael's bloodlust so he will leave Jamie alone. Michael refuses to listen, however, and attacks him; Loomis barely escapes with his life.

Loomis gets a ride from Jackson P. Sayer, who drops him off at the Haddonfield police station. After Michael slaughters several officers in the police station, a group led by Earl Ford emerges from a local bar and they quickly form a lynch mob when Loomis, seeing no other defense for the town, tells them that the monster has returned. Loomis works with Brackett's replacement, Sherriff Ben Meeker, and the few remaining officers to help protect Jamie.

Michael attacks and injures Loomis, who tries to hide Jamie from him. Loomis recovers enough to help Meeker, backed by the state police, gun Michael down, sending him falling down an abandoned well. They throw explosives down the mine after him, seeming to finally kill him. However, Loomis sees the horrific sight of Jamie stabbing her stepmother, dressed in a clown costume similar to what Michael wore when he killed his sister; it seems she has inherited her uncle's evil. Loomis reluctantly prepares to kill Jamie, intent on destroying the Myers family curse once and for all, but Meeker stops him.

Halloween 5: The Revenge of Michael Myers

One year later, Loomis is assigned to treat Jamie at the Haddonfield Children's Clinic. He find out that Michael is still alive and that Jamie is psychically linked to him. He entreats her to tell him of her uncle's whereabouts, but she is too traumatized to respond.

When Michael returns, he kills Jamie's adoptive sister Rachel Carruthers along with her friends, one of whom Loomis unsuccessfully tries to save. After Michael kill her best friend Tina Williams, Jamie agrees to help Loomis. The police and Loomis set a trap for Michael at his old house, and use Jamie as bait by putting her in Judith Myers's bedroom. After the police receive calls about Michael being at the clinic, they all leave, leaving Loomis, Jamie, and deputy Charlie Bloch.

Bloch is ordered to take Jamie to the police station, but Loomis stops him, knowing Michael would still come to the house. Sure enough, Michael arrives, and Loomis tries to reason with him, begging him to fight his homicidal urges and redeem himself by sparing Jamie's life. Loomis' words seem to work at first, as Michael lowers his knife, but when Loomis reaches to take it away from him, the killer slashes him across the abdomen and throws him through the banister.

When Loomis awakens, he appears to betray Jamie, grabbing her and shouting for Michael to take her. He is actually luring Michael into a trap: Loomis drops a metal net over Michael, shoots him with a tranquilizer gun, then beats him unconscious with a wooden plank.

Halloween: The Curse of Michael Myers

In Loomis' final appearance in the original Halloween continuity, it is revealed that Loomis has retired, having suffered a stroke following his previous encounter with Michael. He lives a solitary existence at the outskirts of Haddonfield, choosing not to interact with other people.

In 1995, Loomis' old friend and colleague Dr. Terence Wynn visits him and tries to persuade Loomis to return to Smith's Grove. Loomis declines. While the two are arguing, they hear the voice of Jamie Lloyd on the radio. She is begging Loomis to help her. It turns out that Jamie was impregnated by the same cult that kidnapped her in 1989; however, she succeeds in escaping after giving birth to a baby boy. Then, she takes the child with her and stops at a bus station to call Loomis. Michael tracks her down and kills her, but cannot find the baby; Jamie had left her son in the bus stop bathroom. The child is found by Tommy Doyle, the boy whom Laurie Strode was babysitting in 1978, who has become a reclusive adult bent on destroying Michael Myers. He names the child Steven.

The following morning, Jamie's body is discovered, and Loomis is devastated. He had thought that the last of Michael's bloodline was killed that night, but after being approached by Tommy, who tells him about his discovery of the baby, Loomis knows he has to fight his nemesis once again in order to save the infant.

Tommy tells him to meet him at the campus rally the next night to discuss what to do next. The following night, Loomis meets up with Tommy but their meeting is cut short as they discover the body of Barry Simms falling from a tree. They both know that Michael is now in Haddonfield.

They return to Tommy's home to discover that the baby is missing as well, as are Laurie's cousin Kara Strode and her son Danny, whom Tommy is trying to keep safe. Kara and Danny bang on the door, begging to be let in as Michael is chasing them. Tommy questions Loomis as to who knew about the baby; Loomis replies that only he and Wynn knew. This is when they all hear a voice call out to Danny.

They go into the living room, where it is revealed that Wynn is actually the mysterious Man in Black who had freed Michael after his capture by Loomis years before. Wynn, along with an old neighbor of the Myers family, had placed the Thorn Curse on Michael on the night he killed Judith. Loomis and Tommy are then drugged while Wynn takes Kara, Danny, and Steven with him to his base of operations at Smith's Grove.

As soon as they recover, Loomis and Tommy travel to the Sanitarium, where Loomis intends to deal with Wynn. He tells Tommy to stay put. He finds Wynn in his office, where Wynn reveals he wants to experiment on Jamie's baby to re-create Michael. Loomis is about to shoot Wynn but is knocked out by Wynn's henchmen. They leave Loomis while they go to Steven and Danny. Unbeknownst to Loomis, Wynn and his accomplices are then slaughtered by Michael.

Loomis awakens and searches for Tommy and the others. He finds them running away from Michael and opens the Sanitarium's gate for them. As they get into their car, Tommy entreats Loomis to come with them, but he replies that he still has unfinished business in the Sanitarium. A loud scream is heard from inside the building in which Loomis and Myers were last seen, and the mask of Michael Myers is found on the floor.

H20 timeline

In the H20 timeline, he dies of a heart attack in front of Michael after the latter kills a girl named Elizabeth. He is buried at Mt. Sinclair Cemetery.

Final Timeline

In the Final Timeline, (which ignores the 4-6 and H20 timelines), Loomis stopped being Michael's doctor following the killer's apprehension in 1978. The following year Loomis gave a record statement claiming that Michael should be executed, as there was no point in keeping him alive. At some point afterwards Loomis passed away, and his student Dr. Ranbir Sartain took over as Michael's doctor.

Halloween (Remake) Series

In Rob Zombie's 2007 remake of Halloween, Samuel Loomis is a child psychologist who works at Smith's Grove Sanitarium in Warren County. At one point in his life, he was married, but it did not last long.

On October 31, 1990, Loomis is called by Jim Chambers of Haddonfield Elementary School to arrange a meeting with Deborah Myers. They believe that Deborah's son Michael displays antisocial behavior, so Chambers wants Loomis to treat him. Chambers shows Deborah a bag with a dead cat that was found in Michael's backpack, along with photographs of animals in various states of mutilation. Loomis tells Deborah that Michael is a psychopath; later that day, Michael murders four people, including his older sister, Judith. Michael is institutionalized in Smith's Grove, with Loomis as his primary caretaker.

Initially, Loomis is able to maintain a steady dialogue with Michael, who says he does not remember committing the murders. Michael develops an affinity towards wearing masks, a habit which Loomis does not appear to discourage. As their sessions continue, Michael grows increasingly frustrated with his therapy at Smith's Grove and demands to go home. Loomis occasionally has to remind Michael that he could not go home because of the terrible things he had done.

Loomis notices that Michael is becoming more and more withdrawn; he rarely speaks, and never takes off his mask. Deborah visits him once a week. During one of her visits, Deborah tries to cheer Michael up by giving him an old photograph of himself and his infant sister, Angel, whom Michael calls "Boo". Following the visit, Loomis tries to persuade Deborah to consent to shock treatment for Michael. Just as they enter the elevator, the hospital alarms sounded and orderlies rush into the visitor center, to find that Michael has murdered an attending nurse. Michael is subdued, but the incident has a profound impact on Deborah, who finally realizes that her child is a monster. She commits suicide a short time later.

After his mother's death, Michael becomes nearly catatonic. He barely moves, and stops speaking altogether. Loomis stays with Michael, observing his behavior for the better part of 15 years. Ultimately, he concludes that nothing can be done for him, and resigns himself to the notion that Michael is no longer human, but a creature of pure evil. He resigns as Michael's psychologist; in their final session, Loomis admits that Michael is the closest thing he has to a best friend. He documents his work with Michael in a best-selling book he titles The Devil's Eyes.

One evening, Michael breaks out of Smith's Grove, murdering several staff members in the process. Administrators Morgan Walker and Dr. Koplenson call Loomis at home and he heads down to the sanitarium. After learning the details of the escape, Loomis drives to Michael's hometown of Haddonfield. He goes to the Haddonfield cemetery, where he speaks with the caretaker, Chester Chesterfield. They discover that the headstone for Judith Myers' grave has been removed and replaced with the crucified remains of a dead animal.

Taking no chances with Michael, Loomis buys a .357 Magnum. He then consults with the local sheriff, Lee Brackett, who had heard of Loomis' book, but is not impressed by anything the doctor had to tell him. Loomis insists that Michael is on his way to Haddonfield and that its residents are in danger, in particular a teenage girl named Laurie Strode.

Brackett reveals that, 17 years earlier, he responded to a 9-1-1 call relating to Deborah Myers' suicide. Brackett found the infant, then named Angel, in the house, and, to spare the child the stigma of the Myers name, he omitted her from his official report. He found out a few months later that the baby had been adopted by a friend of his, Mason Strode. Loomis puts the pieces together and realizes that Michael knows that Laurie is his sister.

Loomis and Brackett drive to the Strode house when Brackett receives a 9-1-1 call from Laurie, originating at the Wallace home. They drive to the house, where Brackett finds his daughter Annie bleeding in the foyer, having been attacked by Michael.

Loomis tracks Michael down to the old Myers house and finds the killer just as he is attempting to murder his own sister. He shoots Michael several times in the back, but this only stops him for a few moments. He ushers the frightened Laurie into Brackett's car, but Michael revives and chases after her again. Loomis pulls Laurie out of the police cruiser and into the house. Loomis pleads with Michael to let Laurie go. Michael grabs Loomis with both hands and squeezes his skull, then drags him back inside the house. As Michael pursues Laurie, Loomis, who is struggling to get up, grabs his foot to try and stop him. Michael shakes him off and Loomis loses consciousness.

Following his confrontation with Michael, Loomis is taken to Haddonfield General Hospital, where he recovers from the attack. Michael vanishes without a trace and Loomis believes him dead, blaming the missing body on "police incompetence".

Halloween II

Two years later, Loomis has written another book about Michael, entitled The Devil Walks Among Us, in which he reveals that Laurie Strode is Michael's younger sister. Loomis goes on a tour to promote the book, doing various interviews and press conferences. During one of these conferences, Jane Salvador, Bruce Cabot, and many other reporters start to ask him questions about Michael's whereabouts, to which Loomis angrily replies that the killer is dead. The next day, after Loomis does an interview with a young reporter named Wendy Snow at the Myers house, his publicist Nancy McDonald refers to his campaign as "disgusting".

At a book signing, Loomis meets some of his fans, including Chett Johns, who seems to be more of a fan of Michael than Loomis. Chett's attitude puts Loomis off guard for the next guest: Kyle Van Der Klok, the father of Lynda Van Der Klok, one of Michael's victims. He pulls out a picture of Lynda, and asks Loomis if he knows who she was. When Loomis replies that he does not, Kyle threatens Loomis with a gun, blaming him for his daughter's death. After Kyle is arrested, Nancy tells Loomis that he is toying with people's lives and that there will be serious repercussions. Following an appearance on the Newman Hour, where host David Newman and guest "Weird" Al Yankovic make tasteless jokes about Michael and his victims, Loomis realizes that he is being "an asshole" by exploiting Michael's rampage for profit, and decides to cancel the tour.

Loomis discovers from a news broadcast that Michael is alive and has taken Laurie hostage in a shack outside Haddonfield. Loomis travels to the shack, but Sheriff Brackett, whose daughter Annie has just been killed by Michael, refuses his help.

Loomis makes his way into the shack, telling Brackett "I owe you this!". Once inside the shack, Loomis tells Michael that Laurie needs to come with him, but Laurie has by now suffered a psychotic break and is hallucinating that a young Michael is holding her down. Loomis tries to convince her that no one is holding her, upon which Michael throws him down and kills him by slashing his face and stabbing him in the chest.

Unrated Director's Cut

In this edition, Michael tackles Loomis through the wall of the shack, then picks him up as he removes his mask. Loomis pleaded, "Michael, we're going to Hell...", but Michael stabs Loomis and yelled "Die!".

With Loomis dead, the police open fire on Michael, killing him. Laurie, now completely insane, leaves the shack, picks up Michael's knife and walks over to Loomis' dead body. Against Brackett's orders, the police open fire on Laurie, killing her.


  • The late Peter Crushing, the late Christopher Lee, Mel Brooks, the late Walter Matthau, the late Patrick McGoohan, the late Cesar Romero, the late John Belushi, the late Abe Vigoda, the late Lawrence Tierney, the late Lyle Waggoner and the late Sean Connery were all considered for the role of Dr. Samuel Loomis before Donald Pleasance was cast.
  • Loomis is named after the late John Gavin's character from Psycho.
  • Originally John Carpenter wrote the scene in Halloween (1978) where Loomis calls the Haddonfield police to warn them as a different scene where Loomis calls his wife to tell her what was going on. Donald Pleasence thought it would be better if Loomis had no family. Ironically, in both the comic series, Loomis is given a family. Curtis Richards, author of the novelization of Halloween, chose to use Carpenter's original scene where he calls his wife and lets her know he is alright before noticing the truck with the missing driver and the Red Lounge matchbox on the ground. In the 4-6 Timeline, he is engaged to a woman named Jennifer Hill, while in the H20 Timeline he has a son named David Loomis.
  • Sam Loomis makes the second most appearances in the original series. He is a main character in the first two films and the fourth, fifth, and sixth film. He then has a voice cameo in the seventh. (Portrayed by Tom Kane).
  • Throughout the original timeline, Michael shows an uncharacteristic restraint when it comes to his encounters with Loomis. He frequently restrains and non-lethally wounds Loomis in his pursuit of others. This could be due to Loomis spending many years with Michael, to the point where Michael has some lingering humanity for him. The novelization of the original film heavily emphasized Michael's respect for Loomis as an authority figure and a worthy opponent, a relationship that plays out throughout Michael's stay in Smith's Grove.
  • In the tie-in stories set in the H20 timeline, Michael's restraint seems to have a more devious reasoning behind it. With Michael seemingly and deliberately goading and provoking Loomis, giving him the idea that no matter what Loomis does, he is ultimately powerless against Michael's machinations. This reaches the point that Michael starts moving things around in Loomis' room while Loomis is away and ends with killing Michael's ex-fiancé in front of him, thus causing Loomis to suffer a fatal heart attack.
  • Dr. Loomis was originally meant to appear in a flashback in the 2018 sequel Halloween, in which he was going to be seen trying to kill Michael, only to be stopped by the police. This would have been done with the use of a stand in and special effects. This ended up not happening, and the event was only mentioned in the film instead.
