What's Eating Gilbert Grape is a 1993 drama film based on the book. It stars Johnny Depp as Gilbert Grape and Leonardo DiCaprio as Arnie Grape. This is my all-time favorite Leo performance because his acting in this movie is so amazing (and adorable!) and if I ever get to meet him, I will surely compliment him about this film. Anyways, let's get right to the point: The film is set in the fictional city Endora, Iowa and centers around the Grape family. Arnie is about to turn eighteen years old and Gilbert is twenty. He cares for his brother very much since he has a mental disability. He also makes sure his mother, who is overweight, has almost everything she needs, along with Ellen and Amy. I'm not going to say anymore about this because there's a huge spoiler near the end of the film. But you can see it on Netflix.
