What's Eating Gilbert Grape (1993)

Gilbert Grape (Johnny Depp) is a small-town young man with a lot of responsibility. Chief among his concerns are his mother (Darlene Cates), who is so overweight that she can't leave the house, and his mentally impaired younger brother, Arnie (Leonardo DiCaprio), who has a knack for finding trouble. Settled into a job at a grocery store and an ongoing affair with local woman Betty Carver (Mary Steenburgen), Gilbert finally has his life shaken up by the free-spirited Becky (Juliette Lewis).
