#7: Jennifer Grey as Jeanie Bueller
Jennifer Grey played Jeanie Bueller, Ferris’s tightly wound younger sister who spends the film seething with resentment over his endless good luck. Jeanie is determined to expose Ferris’s truancy, only to unexpectedly bond with a delinquent in a police station and finally let go of her jealousy.

At the time, Grey was in her mid-20s and quickly rising as one of Hollywood’s most promising young actresses. Ferris Bueller’s Day Off gave her a scene-stealing comedic role and set the stage for her star-making turn a year later in Dirty Dancing opposite Patrick Swayze.
