Snow Cake

Finally Sigourney Weaver is not the headstrong scientist or the alpha female anymore. Snow Cake has her in the role of an autistic woman, an accidental mother and one in the center of a horrible tragedy but unaware of it. She is brilliant, so is Alan Rickman who has the other best role in this movie. It is a British movie by Marc Evans shot entirely in Canada, probably that is why it didn't capture much of US's indie audience attention. An interesting movie could also be considered a window in to the world of autism without being very technical about it.
