“What’s Eating Gilbert Grape” is organized in the three-act structure, as is classical film story with a beginning, middle and end including major plot points.

It will be a romance that brings great changes for the Grape family. Also a part of Act I is the catalytic event of the story, which happens when Arnie climbs to the top of the water tower and Gilbert convinces him to
