17 Again is a 2009 American fantasy comedy-drama that uses age reversal to explore family relationships, regret and personal growth. Directed by Burr Steers, the film follows Mike O'Donnell, a man stuck in a stalled marriage and an unfulfilling life who is mysteriously transformed into his 17-year-old body. The story places an adult mind back in adolescence, allowing the protagonist to re-enter his children's high school world and reassess decisions that shaped his family.

To avoid alarming his family and to investigate what went wrong, he adopts his youthful identity and enrolls at his teenage son's high school. Through relationships with his children and a fresh look at his wife, he begins to understand the consequences of his choices and seeks a path to reconciliation.

The tone balances broad comic set pieces — fish-out-of-water scenes in a high school — with quieter family drama as the protagonist learns empathy and humility.
