CANADIAN CAN-CAN (1967)

Inspector Clouseau is posted with the Canadian Mounted Police to study their crime investigation system and is assigned to apprehend a villain named Two-Faced Harry, who actually has two faces, one deceptively honest-looking, the other malicious. Clouseau doesn't realize these two faces are of the same man until he has chased the two-faced freak into the snowy plains of Manitoba.
