Sam (Sean Penn) is a mentally retarded man living in New York who has fathered a small girl (Lucy). The mother has disappeared and he is left to raise the baby. Seems implausible, but the scripting is so strong that it is totally believable. It is also believable that when Lucy is seven, she is taken into custody and Sam must fight for her. And somehow, the overworking lawyer-who-ignores-her-own-son character of Rita (Michelle Pfeiffer) ends up taking his case.
This is another film that totally challenged my prior expectations. To be fair, I had this film recommended to me by someone who also recommended The Butterfly Effect, which I truly believe to be one of the worst films ever made. I am Sam is an excellent film that was nominated and won a whole heap of awards, and rightly so.
