Which film is the clip from? ( PROBABLY NSFW, AS PIC DEPICTS BLOOD )

Hi all, I was browsing one of those widescreen wallpaper websites and as you do, I liked quite a few of the wallpapers and downloaded a whole load of them until I came across this clip from a film.

I've seen other clips of the movie but have thus far been unable to pin it down, I think its from the film, Let The Right One In, but I was hoping someone on here could tell me the name of the film from looking at the still so I can go about purchasing said film as it looks good from the few stills I've seen elsewhere.

Hope someone can put me out of my misery as its REALLY bugging me not knowing what film it is called :P


EDIT: Hah, turns out it was Nightmare on Elm Street, didn't remember the scene :D (Image thumbnail removed)
