What's Eating Gilbert Grape is a 1993 dramedy movie directed by Lasse Hallström and starring Johnny Depp, Juliette Lewis and Leonardo DiCaprio. It is based on a book of the same name by author Peter Hedges. It was filmed in Manor, Texas. The original music score was composed by Alan Parker.

In the small town of Endora, Iowa, Gilbert Grape (Johnny Depp) is busy caring for his mentally handicapped brother, Arnie (Leonardo DiCaprio). His morbidly obese mother, Bonnie (Darlene Cates), has not left the house in seven years since her husband committed suicide by hanging himself in the basement of their house, spending almost all of her time on the couch watching television. With Bonnie unable to care for her children on her own, Gilbert has taken responsibility for repairing the old house and looking after Arnie, who has a habit of climbing up the town water tower, while his sisters Amy and Ellen do the rest. A new "Food Land" supermarket has opened, threatening the small Lamson's Grocery where Gilbert works. With all the weight on his shoulders Gilbert tries to handle his situation the best he can.

As the film begins, the family is preparing for Arnie's 18th birthday. Just then, a young woman named Becky (Juliette Lewis) and her grandmother are stuck in town when the truck pulling their mobile home breaks down. When Gilbert first sees Becky, he begins to rethink his life. His unusual, chaotic home life threatens to get in the way of their budding romance. A week into the movie, on the night following Arnie's 18th birthday party, the mother climbs the stairs of her house to her bedroom for the first time since her husband's suicide and dies for reasons not mentioned in the film directly. The children, not willing to let their mother become the joke of the town by having her corpse lifted from the house by crane empty their family home of possessions and set it ablaze, to cremate their parent. The film cuts to the blaze and fades out with the family looking on at their burning home.

The story then skips ahead one year, with Gilbert describing how Amy got a job in Des Moines, and Ellen who can't wait to switch schools, as Gilbert and his brother Arnie wait by the side of a long road for the arrival of Gilbert's romance, Becky. The film fades out with Gilbert and Arnie riding with Becky and her grandmother to an untold destination, hugging each other in the back seat of the Recreational Vehicle owned by Becky's grandmother.
