Bill Denbrough (remake)

William "Bill" Denbrough is the main protagonist of Stephen King's It. He is the leader of the Losers Club, ever since he lost his then-six-year-old brother George to the title adversary. He blamed himself for it, and his parents blamed him too. He became friends with the other members, who became his followers. He is the arch-enemy of IT (Pennywise the Dancing Clown).

In the 2017 film, he is portrayed by Jaeden Lieberher as his younger self, whi also played Henry Carpenter and by James Mcavoy as his adult self in the 2019 sequel, who also Charles Xavier, Gnomeo, Wesley Gibson, and Hazel.

Personality
Bill has been steadfast for most of his life, using his bravery and instinct to unite his friends in turmoil and is also a talented writer, even from a young age he would write stories in his room with the typewriter his parents gave him. Though he is a brilliant wordsmith, Bill's verbal speech is nowhere near as finely tuned since Bill has a severe speech impediment for the entirety of his childhood.

Bill overcame his stutter during his teenage years due to a private speech therapist, however his stutter returned unexpectedly after having received a call from Mike Hanlon summoning him back to Derry.Bill's stutter noticeably gets worse when he is upset, angry or afraid. The speech impediment will sometimes not be apparent such as he when he is reading a different language, doing a impression (e.g Henry Bowers) or when he is making a speech. It's because of his stutter that caused Henry Bowers and many others to bully Bill viciously. Although upset with being treated in this manner, Bill doesn't mind his friends poke gentle fun at his stutter.

Bill's greatest attribute is undying love for his younger brother Georgie, which only strengthened when Georgie was brutally murdered by IT. Bill uses Georgie's memory as a guiding light to destroy Pennywise. While his love for Georgie is endearing, it's also a great source of guilt, as he feels Georgie died as a direct result of helping Georgie make the paper boat that ultimately led to his death. Though he is told by Richie that it isn't his fault, the guilt follows him throughout his childhood and adulthood and enables IT to torment him by making illusions of Georgie. After Georgie's death, Bill's parents grow distant and begin to neglect him, to the point that he wonders if they ever loved him at all. His relationship with his parents never recovers. Decades later, Bill is still convinced that he is to blame for Georgie's death and doesn't recognise that what his parents did to him was wrong and abusive. This doesn't change until IT forces him to confront his greatest fear by turning into Georgie and accusing him of being the reason Georgie died.

Bill is shown to be reckless and impulsive on multiple occasions, especially when he is face to face with IT. But despite his headstrong demeanour, Bill is extremely intelligent and shows great maturity. He has the power to pull the Loser's Club together through the horrors that IT sets upon them.

The 2017 version further expands on Bill's character flaws, as he shown to be more delusional in thinking that Georgie must have survived and takes the majority of the movie to come to terms with his brother's death. And while he is undoubtedly a good leader and friend, Bill has issues concerning people telling him of Georgie's fate, as he pleaded with his father that it was possible Georgie could be still alive, even showing his father a diagram model of the Derry sewer system to no avail. Bill even punched Richie down when the latter stated Georgie was dead, though he apologized to Richie later when Beverly was captured by IT. Despite his earlier headstrong and reckless behavior, Bill is completely willing to allow Pennywise to feed on him while the others escape, saying it was his fault they were in danger in the first place.
