Peter Lorre is perfect in this role, a calm, controlling madman with a terrifying temper bubbling underneath. Flashes of his temper are the highlights of the movie. Whomever played his wife could've probably been out-acted by a beanbag, but she's pretty, so it's ok. The other main man was okay, and I was rooting for him like I was supposed to. I guess the underlying question is: Could an island of slavery actually exist? Just kidding. The movie is not that deep, or worthy of further thought. The underlying question actually is: What does Peter Lorre have against monkeys?
