Mark Twitchell was a 29-year-old guy from Edmonton, Canada, who wanted to make movies for a living. He went to film school and even made a Star Wars fan movie that had a small part featuring a real actor from the original films.
But while Twitchell seemed like a normal person trying to break into Hollywood, he had become seriously obsessed with the TV show Dexter. The show is about a guy who works as a blood expert for the police but secretly goes around killing bad guys.
