I am Sam is a film which follows the story of a man with the mental age of a seven year old, as he attempts to regain custody of his own seven year old daughter. This film is beautifully crafted and where sentimental could have become mushy Sean Penn ,Dakota Fanning and the rest of a brilliant cast stop this happening. I think that Sean Penns' portrayal of Sam far outshines similar performances such as Dustin Hoffman in rain man. All in all this is a highly entertaining and enjoyable film , well worth a viewing with an excellent cast.
