William Castle "horror" movies don't get much more harmless than this, a simplistic and good-natured romp starring Tom Poston (of Newhart fame). Poston stars as an American in England, invited to visit an eccentric man's mansion, where other eccentric characters quickly find themselves killed. Goofy humor and really cheap fright gags abound. You'll forget it the moment it's over, though it should go without saying that you can never have too much Robert Morley in a movie.
