I'm still waiting for a really good film to be made using the Cthulhu mythos in films. There have been a few so far, but either suffered from low-budget, or didn't capture the 'cosmic horror' elements that HPL wanted to convey. I've always thought "At the Mountains of Madness" or "The Whisperer in the Dark" would make good films; you could argue that John Carpenter was inspired by HPL in his adaptation of The Thing, and a lot of aliens or demons in films seem to show a "Lovecraftian" influence
I'll list the Cthulhu films that I know of, if anyone knows of more please add more:
The Dunwich Horror - directed by Daniel Haller
Dagon - directed by Brian Yuzna
The Beyond - another Brian Yuzna
Reanimator (1-3) - Brian Yuzna (hmm, I see a pattern developing)
The Mouth of Madness - John Carpenter
Also, I'm sure a Stephen King short-story was filmed that seemed to owe a lot to "The Colour from Space"
