The pale man, from Pan's Labrinth.

Doug Jones does creepy very well.

Frunobulax (FZ)

Lucas aka Sinful

The 1938 version of 'Frankinstien" with Boris Karloff as the monster......

i know this isn't a movie monster but the necromorphs from deadspace are creepy but not by themselves the setting and way the game looks makes them shit scary.

i say the cube it self from Cube 2 hypercube2.

John Kerry.

I found a place where we can all vote on this and be able to really see what people think entertainmentRankings.com

Godzilla,enough said.

Not a movie, but ranks amoungst the best monsters.

Man without a face from 'Sapphire and Steel Adventure 4'

In this climatic scene Sapphire and Steel have discovered that the missing person they have looking has been trapped inside a photograph by a creature that has escaped the corridor of time. The creature has recovered the photograph from them...

If you want to stick religiously to movies then how about the monster from Morpheus's mind in The Forbidden Planet.

Hhhm, I would have to say my top 5 great movie monsters are:

#1.) The Alien from "Alien" - and all of it's spawnings - the Alien Queen, the Alien Runner, the Face Huggers, the Chest Bursters, the Predalien from AvP: Requiem (especially when it's around pregnant women, lol), etc. The Alien just wins, hands down.

#2.) The Predator, from the movie of the same name.

#3.) Unicron, from the animated "The Transformers" movie.

#4.) The green orb from "Heavy Metal".

#5.) The Lord of Darkness, from the movie "Legend" - Tim Curry ftw.

And the runner up is:

OMFG... the "Fluke Monster" from that one old ass episode of "The X-Files". I know it's not from a movie, but... damn... sometimes I still get creeped out and nervous when I go to take a shit because of that episode!

Honorable Mentions:

#1.) The Rancor, from "Return of the Jedi"

#2.) The Balrog from "The Fellowship of the Ring".

#3.) The Stay-Puft Marshmallow Man from "Ghostbusters".

I meant Godzilla himself, not the movie by the the same name.

the jaber wocky from the live action alice through the looking glass

had nightmares for a week after that when i was a kid

mary poppins!

Zorak, Moltar, Brak...

The Spiders from Arachnophobia.
Seriously. I think that movie is the sole reason I hate spiders so much.

Why don't they just step on the spiders?  The sound effects would be much simpler to mach than by stepping on mustard packets and chips. 

I hated that movie though, scared the crap out of me, and made me even more arachnaphobic than I already was.

another movie to give you a complex i was affraid to turn on a light switch or put on shoes for a month after that one

course bein only 8 at the time bein barefoot wasnt all that bad lol

I agree with almost all of the above. Just wondering if anyone remembers "5 Million Years to Earth" based on the

Quartermass character and the story "Quatermass and the Pit". Watched it when I was 6 Years old. Nightmares for a

month!

I'm not no movie monster silly Spaceghost!!  You need a baloney sandwich!   I like a beautiful baloney sandwich.  Oh boy oh boy!

Greatest movie monster would have to be Jason Vorhees. he can't be stopped, he can't be killed. Hell, they killed him twice and he came back from the dead to kill some more.

Actually, I remember reading in an interview with one of the creators of the original Godzilla that not only was the Hollywood CGI version "unanimously approved" by the comittee that regulates Godzilla merchandise, but that the CGI version was more or less the Godzilla they wanted to do back in the fifties but had to settle for a guy in a rubber dinosaur suit.

No contest.

PS. Watching Aliens when you're three is a bad idea.

No one has mentioned the "Dogs" from Ghostbusters, either.  Maybe is was just me but I didn't like the part where she was sitting in the chair and they drug her in the bathroom and molestered her.  It creeped me out for a few weeks because the bathroom in my room was directly across from the chair I sat in to watch TV.  Of course, I was also around 8 years old...I didn't know it was a comedy at the time.

I rest my case...

TROGDOR!!!

Haha...
