6. Fido (2006)
What is so different about it? Well, for starters, the titular zombie is played by acclaimed actor and world famous comedian Billy Connolly. How often does the role of a zombie get taken by such a major talent? But then there's also the fact that the movie takes place in a 1950s-esq alternate universe in which radiation has turned the dead in to zombies and the zombies in question have been domesticated. It's an enjoyable little movie with a fresh approach to zombies and has generally received a positive response. It currently holds a 70% rating on RottenTomatoes.com.
Why have you probably never seen it? Despite boasting a stellar cast that includes the likes of the aforementioned Billy Connolly, Tim Blake Nelson and Carrie-Anne Moss, the film only got a limited release, earning just $304,533 in the United States and a total of $426,224 worldwide, with domestic DVD sales of $2.95million. It simply wasn't that big of a movie.
