Comedian Mike Birbiglia apparently suffers from a major sleepwalking problem, and this semi-autobiographical film takes a funny and sometimes shocking look at it. Birbiglia essentially plays himself, a struggling standup comedian who is trying to sustain a relationship with his girlfriend (Lauren Ambrose). He seems rather mellow during the day, but is prone to nasty and violent sleep episodes, during which he acts out what’s happening in his dreams, and he nearly kills himself numerous times. Birbiglia directed along with Seth Barrish, and the film is one of the year’s more-pleasant surprises. David Wain makes a brief cameo, as does comedian Marc Maron as a thinly veiled version of his marvelously sarcastic self.
