Irish playwright Martin McDonagh, who made his feature film debut with the excellent In Bruges, shifts focus to the sunny, meta-textual hills of Hollywood with the fiendish Seven Psychopaths. A neurotic Colin Farrell plays a screenwriter named Martin, attempting to finish a script for which he only has a title (“Seven Psychopaths”). Figuring it out means bouncing ideas off of his loopy best friend, Billy (a tremendous Sam Rockwell) and Billy's dognapping business partner (a soft-spoken Christopher Walken). Plans hastily change when Billy takes the beloved Shih Tzu of a violent mobster (Woody Harrelson), a masked serial killer starts offing mafia members, and a mysterious drifter with a bunny (Tom Waits) shows up at Farrell's door with a killer story. A meta-farce about storytelling, McDonagh also crafts a movie about the the incomplete narratives of human life. Equally violent, sad and funny, Seven Psychopaths is just crazy enough to work.
