Firefly has quickly become a cult classic, after it was cancelled by Fox in 2002, after airing only 11 episodes (out of order). Firefly was created by Joss Whedon who is best known for creating Buffy the Vampire Slayer and is set to direct and write The Avengers movie set for release in the summer of 2012. Firefly is a space western set in the 25th century where the renegade crew of the Serenity try to stay one step ahead of the long arm of the Alliance.
