A pastiche of Hitchcock, Agatha Christie, and screwball comedy, this 2003 Swedish film is delivered with such gusto that one can forgive its lack of originality. Most of the action takes place aboard a train from Stockholm to Berlin, where a pompous doctor and his nubile mistress are plotting to kill the doctor’s wife; among the other characters are an elderly spinster who befriends the wife and a klutzy literary critic who inflicts a number of increasingly debilitating injuries on a returning war hero. Sumptuous black-and-white cinematography enhances this genre exercise, which is engaging despite a rather predictable ?surprise? ending. Peter Dalle directed. In Swedish with subtitles. 100 min.
