Little Things (2007)

Jack Watson has extreme Obsessive Compulsive Behavior. All his life, he has dreaded even the simplest of tasks. When he tries an unconventional cure, his entire world is turned upside down as zombies from his past haunt and hunt him down. It is when Jack finally takes control of his OCD that he truly becomes the hero, rescuing the girl of his dreams, and ultimately deciding his own fate. As a young boy, Jack Watson was a big zombie movie fan. One day while watching a very scary one, he unconsciously pours way too much salt on his popcorn. Unfortunately, 10 year old Emily catches him and laughs at him. From then on, he becomes more and more withdrawn into the world of O.C.D. He can hardly function. But when Emily (now an adult) moves in next store, he loses his mind. He starts seeing zombies everywhere, all of them the people who made fun of him. He happens upon an amateur hypnotist, who puts him in a post-hypnotic trance and is instantly transformed into a confident human being with the simple sound of a ringing bell. "Cured", he gets on with his life. Until he hears a bell again. Soon he finds himself flashing back and forth between his "discomfort zone" of O.C.D. and his "in control" mode of confidence and rationality. Meanwhile, Emily's life is in danger because of some gangsters who want to silence her. Will Jack save Emily? The person who traumatized him when he was a child, leaving him forever trapped in the very black or white reality of his mental handicap.
