THE WINTER GUEST (R) Alan Rickman's delicate construct of linked vignettes on a theme of thawing one's heart in a cold climate (in this case, a Scottish seaside town). Emma Thompson plays a grief-frozen young widow, cajoled by her mother (real-life mum Phyllida Law) into getting on with living. There's pleasure to be had in watching the two stars have at it, with bohemians-via-Hampstead flair. B (#414, Jan. 16)
