Set in the Arctic, Claudia Llosa's film — starring Jennifer Connelly as a single mother and Cillian Murphy as her grown son — seems keen on remoteness, lack of warmth, and perpetual dusk. This is one of those movies with a deep aversion to telling you anything directly, except that tragedy has befallen its characters, with Llosa's willful narrative ellipses freezing out the feeling of whatever tragic pietà its maker may intend.
