But the creepiest actor ever is Christopher Waltz, a Nazi official who appears throughout the movie. He has the sliminess of Hannibal Lecter, but he's scarier because he's not locked up. Watch him, actually listen to him, as he spears a creampuffy dessert.
Be forewarned that Tarantino isn't afraid of a little gore here and there. But the violence, severe though it is, is paced throughout the movie; it's not like wading through a pool of waist-high blood. And you can bet that Waltz will be getting a nomination at Oscar time.
