Arthur Christmas

(PG) ★★★☆☆

From the British animators of Wallace and Gromit comes this 3-D digital movie that’s excellent. The film exposes how Santa manages to deliver presents to every child in the world in one night—it’s an elvish military operation from a 2-mile-long spaceship. The latest Santa (voiced by Jim Broadbent) is due to hand over the reins to one of his sons, possibly Steve (Hugh Laurie). But the younger son, Arthur (James McAvoy), and his Grandsanta (Bill Nighy) rush out to save the day.
