Focus Features has released the trailer for It’s Kind of a Funny Story. In perfect casting, Zach Galifiankis plays a mental patient who helps a clinically depressed teenager (Keir Gilchrist) get a fresh start after checking into a psychiatric ward. Basically it’s the self-committal version of One Flew Over the Cuckoo’s Nest. Emma Roberts, Lauren Graham, and Viola Davis also star.

The film is directed by Ryan Fleck and Anna Boden, the team behind the utterly depressing (in a powerful way) Half Nelson. It’s nice to see they’re taking on lighter material, like people with mental disorders instead of heroin addictions. Galifianakis could portray both afflications equally well.

It’s Kind of a Funny Story checks into theaters Septembe 24, 2010.
