Our Idiot Brother is a bargain of a film. You don’t get just one film that centers on Paul Rudd’s adult-child stoner, Ned Rockliffe, but three additional films in which Ned causes chaos in sisters’ lives.
Ned is released from prison after serving time for selling a stash of marijuana to a policeman. Ned’s girlfriend, Janet (Kathryn Hahn), kicks him off their farm and keeps his dog, Willie Nelson. He ends up living back at home with his eccentric mother, Illene (Shirley Knight).
After he leaves his mom is when the story breaks itself down.
