Neomaniacs

After Lars Fricke fails to imitate Gollum in an art-house cereal commercial, the director gives him three days to learn how to act schizophrenic or he's fired. Secretly to anybody but Lars and himself, his manager Freddy transfers Lars to a mental institution so he can improve his method acting skills. After the first days treatment (including electroshock therapy) Lars wants to abort his stay but his Manager dies in a car accident and now nobody knows about his non-obligatory stay.
