A while back, I saw a movie, or rather part of a movie, and I can't remember what it's called. It was on the scifi channel, if I remember correctly. The only part of the movie that I can really remember is near the end (I think) where a girl kills the killer/monster by throwing a roll of movie film into a fire. I am pretty sure that the monster came out of the film. Any ideas ?

"Cut"?

I seem to remember that movie ending like that. Could be wrong.

That sounds right to me.
