Life is fleeting. And if you're ever distressed, cast your eyes to the summer sky when the stars are strung across the velvety night. And when a shooting star streaks through the blackness, turning night into day... make a wish and think of me. Make your life spectacular. I know I did. I made it, Mom. I'm a grownup.
~ Jack's valedictorian speech.

Jack Powell is the titular protagonist of Jack. He is a 10-year-old boy with a rare disorder that causes him to physically age at an accelerated rate, making him literally a child in an adult's body.

He was portrayed by the late Robin Williams, who also portrayed Mork in Mork & Mindy, Popeye in Popeye, John Keating in Dead Poets' Society, Peter Banning in Hook, Sean Maguire in Good Will Hunting, Daniel Hillard in Mrs. Doubtfire, Alan Parrish in Jumanji, Phillip Brainard in Flubber, Lance Clayton in World's Greatest Dad, Genie in Aladdin, Batty Koda in Ferngully, Rainbow Randolph in Death to Smoochy, Fender Pinwheeler in Robots, Dan Rayburn in Old Dogs, Theodore Roosevelt in the Night at the Museum series, and Ramón and Lovelace in the Happy Feet franchise.


Jack is first seen as a newborn by his parents Brian and Karen. He has a rare disorder in which he physically matures at an incredibly fast rate, to the point that he will grow physically old and die when he is still at a young chronological age.

Ten years later, he is now a child stuck in an adult's body. On his first day of a new school year, a group of four boys bully him, but he scares them away by dipping a fake eye into slime and throwing it at them through the window. His tutor, Lawrence Woodruff suggests that he should attend school. His parents had agreed at first. On his first day of school, he is exploited by the other kids to win at a basketball game against the school bullies. He also got adult magazines and other items. At first, he had to be normal, but begins a relationship with his teacher, Miss Marquez, but goes through a fall and is taken to the school nurse. Because of his Werner syndrome and the dangers of his health, his parents decide to withdraw him from school, much to his dismay. Jack sneaks out of the house and goes to a bar where he ends up being drunk and meets a man named Paulie, but he gets into a fight with a bully and the two get arrested. After being released from jail, he decides to lock himself in his room and decides to stay in there after realizing that the outside world is too dangerous for Jack. Karen becomes concerned about Jack. However, his friends show up at his house and asks if Jack can come out and play. Eventually, Louis brings all of his friends as they shout out "Can Jack come out and play?" and Jack finally leaves his room and begins to do the fun activities. The next day, he finally returns to school and continues the rest of elementary school. Seven years later, Jack is now an old man and is at his high school graduation as class valedictorian and delivers his speech to his friends and his parents. At the end of the film, he is last seen driving away with his friends as they begin their future together.
