Christian Slater, Steve Buscemi and John Cleese have signed to the animated comedy, Igor for Exodus Film Group and the Weinstein Co.
The three actors are reprising their voices from the short film version of the movie, which also starred Jay Leno. Variety reports the film is a twist on the monster genre that follows a mad scientist's hunchbacked lab assistant who has big dreams of winning the Evil Science Fair. Slater will voice the lead role of Igor, with Buscemi as Scamper, an intelligent, sarcastic lab rabbit; Cleese lends his voice to Igor's evil master.
Chris McKenna is writing the script for Igor; a 2007 release has been scheduled.
