Oh, the best Lovecraftian interpretation that I'm aware of was "The Case of Charles Dexter Ward," starring Vincent Price in the title role (I've only seen the last half hour of it on AMC, but, except for a love story tacked in by Hollywood, it followed the book fairly well - I don't know if they kept the title or not). "The Dunwich Horror" managed to catch the FEEL of Lovecraft's book, but ignored all of the elements of it except for names, and made it a very typical sixties horror film. It's a fun movie. Oh, "The Colour Out Of Space" is an interesting, disturbing story - and it spawned two movies, each taking a few steps farther from the original... Both were titled "I Married a Monster from Outer Space."
