A lonely old geezer gets a little soul-defrosting from three free-spirited women in “Snow Cake,” a heartfelt but utterly predictable indie drama.

Alan Rickman holds the film together as an Englishman with a secret who, against his better judgment, gives a ride to a wacky teen hitchhiker in Canada who gets killed when their car is hit by a truck. So the Brit seeks out the girl’s mother (Sigourney Weaver), who turns out to be autistic.

Weaver’s Rain Man act (flailing, squawking) instantly grows tiresome, and the story is driven by coincidence and unlikelihood. The mother’s gorgeous neighbor (Carrie-Anne Moss) hurls herself at the staid old Englishman strictly because the script needs a love story, not because there’s any plausible connection between them.
