Dark Chocolate M&M's

I discovered a game on the M&M website. It's to promote their new Dark Chocolate M&M candies (dark is the best!). They created a spooky painting with some of the M&M characters scattered in, and there are clues in the painting to help you decode the titles of 50 "dark" movies. I have only gotten 16 so far, but I am not one to watch spooky movies, thereby limiting my knowledge of dark movie titles. If you'd like to test your knowledge, try the link I've created to the right. Can you get them all? Let me know if you do!
