Cult filmmaker James Gunn, who made Tromeo and Juliet and Super and wrote the screenplays for Dawn of the Dead and the two Scooby Doo movies, has written and directed a video game. It's called Lollipop Chainsaw and it's his first foray into that business. Gunn talks about how freeing it is to write a 1000-page video game and how being part of an 'artform' that's still developing was exciting to him.
