When was the last time you saw a new movie set during the 1840s? The era is the first oddball thing about "Ravenous", though by no means the last. This provocatively weird movie is essentially a vampire film crossed with the Donner party, that unfortunate band of hungry pioneers who got stuck in the wilderness with only themselves to eat. The setting here is Fort Spencer, a dismal collection of shacks huddled in the snows of the Sierra Nevada mountains. Mid-winter, a nearly dead Scotsman (Robert Carlyle, from "The Full Monty") staggers into camp with a story of desperate cannibalism. The skeleton crew (so to speak) manning the fort sets out to investigate, when... ah, but the twists and turns of this dark yarn should remain shocking. Be assured, however, that the cannibalism has just begun; this movie has cannibalism like "Titanic" had an iceberg. Director Antonia Bird ("Mad Love", "Priest") blends some humor into this scenario, especially in the final reels, but otherwise this is a fairly serious gore picture; a confused Twentieth Century Fox tried to market it as a black comedy, and the movie flopped anyway. It deserves a better fate--at the very least, it's not quite like anything else out there. The music, a brilliant collaboration between Michael Nyman ("The Piano") and Blur's Damon Albarn, is an offbeat blend of period twang and modern drone. Carlyle and Guy Pearce (of "L.A. Confidential") are fascinating in the lead roles--their sunken faces would look at home in Civil War photographs--and the eccentric supporting cast, including Jeremy Davies and David Arquette, adds flavor to the dish.
