my fave is the fire extinguisher and face hits action in Irreversible

Thats easy, Mrs Carmody from The Mist.

Never have I disliked a character in a horror flick more.

The creepy, red mac wearing midget from 'Dont Look now' simply because I hate anything to do with achilles heels being slashed etc..and thats all hes gonna be able to reach really.Hes fooked if im wearing my dms I guess.
Not a horror character as such but the child catcher from chitty chitty bang bang is pretty terrifying!..Death by lollipops!

Arrr yes, I couldn't stand the scene in 'Pet Semetery' where the kid slashed the back of the dude's foot. Knocked me sick!

Who would want to be stuck in a room with any horror character? You wouldn't last long. Human or not horror characters don't play around.

I know you don't like japanese horror but I really think you would like Red Room-
www.imdb.com/title/tt0371516/
you wouldn't want to be stuck in the same room as the hairdryer or light bulb in that film

Jason,michael or leatherface

Any reason why? :)

Somewhat on topic, can you imagine a "Cabin in the Woods" type movie where they get clearance to use actual horror franchise characters, during THAT scene.... if you saw the movie you know what i'm talking about.

Leatherface as he will catch you and potrntially saw your leg off.Jason and michael will hunt you for no reason
