Exploring the dark side

Here's a great time-waster, courtesy of PLANET3RRY.

To promote their new dark chocolate M&Ms, and to tie in to Halloween, M&Ms has launched a clever online game. This picture contains images that represent the titles of 50 "dark" movies. When you think you see one, click on it and type your guess in to see if you're right.

How many can you find? I've been working on this for a while now (you cansave your game and come back to it later) and I'm stuck at 35 out of 50. Some of them are pretty obvious. Others, not so much.
