The Midnight Meat Train is a 2008 horror film produced by Clive Barker, and based on the short story of the same name.
Leon (Bradley Cooper) is a vegan and a photojournalist who seeks out unique and harsh scenes from his city to photograph and sell. However, after a gallery owner criticizes his work for being too "safe", he heads out into the subway late at night. There, he comes upon an attempted rape, and photographs the scene before intervening to save the victim. However, the next day, Leon discovers that the woman he saved has gone missing. With some investigation, he learns that she is one of many people who have gone missing around the subway at night, and this leads him to discover a butcher named Mahogany, whom he believes is the key suspect of these subway murders.
