Lonesome Jim

Jim is a young man who, after deciding he can't make it on his own, moves back to his hometown in Indiana -- under his parents' roof. He's saved from his family's dysfunction by a local woman and her son, who sees him as a father figure.

Lonesome Jim is a 2005 American comedy/drama film directed by Steve Buscemi. Filmed mostly in the city of Goshen, Indiana, the film stars Casey Affleck as a chronically depressed aspiring novelist who moves back into his parents' home after failing to make it in New York City. Liv Tyler also stars as a good-hearted nurse who finds contentment through encouraging optimism in Jim's glum world.
