People who are different are magical! That’s the takeaway lesson from Snow Cake, an awfully tidy, infernally sparkly study in skewed blessings, made manifest by Committed Acting from Sigourney Weaver. She plays an autistic Canadian whose daughter dies in a car accident. The girl was a hitchhiker; the blameless driver who picked her up is a bitter ex-con (Alan Rickman), and although he just stops by to pay respects, his heart thaws thanks to the mother’s childlike spirit and some great sex with a neighbor (Carrie-Anne Moss).
