The animated film is based on the comic book "Cerebus the Aardvark", considered by many to have started the indie alternative comic field. It started in 1977 and ran for 300 issues and holds the Guinness World Record for "Most consecutive issues of a comic-book drawn and written by one person". The comic's creator, Dave Sim, told us there was a 99% chance he would not approve of our film, but against all odds upon finishing the film he gave a thumbs upon completion. Our film is the first CGI feature to be done on no budget in history. He has previously turned down George Lucas, DreamWorks and Paramount.
