Not doing favorite cute monsters (sorry Muppets and Monster Inc.) I'm even leaving out Hellboy because he was meant to be the hero. Only monsters that were meant to be scary.
10) SNAKEMAN (Tommy Ray) in "Dreamscape" (1984) Creepy, cheesy and smart-mouthed, the stuff bad dreams are made of.
9) The ID (Evil Dr. Morbius) in "Forbidden Planet" (1956) Disney animation makes its first of two appearances on this list as cartoonists drew an alter-ego run amuck in this MGM Science Fiction classic.
8) DRAGON (Maleficent) in "Sleeping Beauty" (1959) Disney could truly scary, and not just for the tots. The other great film dragon was in "Dragonslayer", but that was just a creature trying to get a good maiden meal and this one was truly evil.
7) LITTLE GIRL ZOMBIE (Karen) in "Night of the Living Dead" (1968) I decided to pick just one zombie, so I had to go with the undead tot in the basement.
6) CREATURE OF THE BLACK LAGOON in "Creature of the Black Lagoon" (1954) - The last of the classic Universal monsters. Was happy to get to see this in old school 3-D.
5) ALIEN MOTHER in "Aliens" (1986) - Tough between this one and the one in the first House of Horrors film, but love its battle with Meca-Ripley.
4) FRANKENSTEIN'S MONSTER in "Bride of Frankenstein" (1935) - Karloff in this film edges out his debut as the creature (and the also great Universal monster, Mummy) because he is so eloquent in this film ("Friend!")
3) GODZILLA in "Gojira" (1954) - Because who wouldn't want to stomp through cities like the big guy.
2) KING KONG in "King Kong" (1933) - As Dino said, "No one cries when Jaws dies... But when Kong dies...People cry."
1) THE WOLFMAN (Lawrence Talbot) in "The Wolfman" (1941) - Sure, he looks nothing like a wolf (unlike the great wolf people in "The Howling" and "An American Werewolf in London"), but I love the way the poor guy looks. Can't explain why I've always loved the guy, and he's always been not just my favorite Universal monster, but overall monster. (Someday, I want a cane with a silver wolf head. Is that so much to ask?)
