Michel Hazanavicius likes trying on different eras for size. Known primarily for OSS 117, his cheeky parody of 1960s spy movies, the French director's gotten more serious, and consequently more charming, with his latest. The Artist is the story of a silent film actor in decline, told as an actual silent film. It sounds gimmicky, and sort of is, but the sincerity of the delivery and the attention to detail make for a winning re-creation of a bygone age.
