Just found this new horror movie called "The Man Who Collected Food"! Don't think the movie is actually out yet but the trailer can be found on youtube:

It follows a man so obsessed with collecting food that he says that he has to resort to cannibalism! Haha it looks like a blast! Definitely a new take on the whole cannibalism in movies genre!
