Exodus Productions executive producer Max Howard announced today that John Cusack and Emmy award winner Sean Hayes have joined the voice cast of its CG-animated feature comedy Igor, directed by animation veteran Tony Leondis (The Prince of Egypt, Lilo & Stitch 2) from a script by Chris McKenna (TV’s American Dad).

Cusack will voice the title character, a potentially gifted and brilliant scientist, while Hayes will play one of Igor’s inventions/sidekicks. “John and Sean are both terrific actors and ideally cast in their roles, said Leondis. “We couldn’t be more excited to have them join an already fantastic voice cast.”

Igor is an irreverent comedy that brings a new twist to the classic monster genre. It tells the story of a hunchbacked lab assistant who is forced to serve a cruel taskmaster named Dr. Glickenstein (voiced by John Cleese), but harbors big dreams of becoming a scientist himself and winning the annual “Evil Science Fair.” Cusack’s good buddy, Jeremy Piven, voices Dr. Schadenfreude, Igor’s nemesis. Other inked voice talent, alongside the aforementioned Cleese, includes Jennifer Coolidge, Molly Shannon, Steve Buscemi and Jay Leno.

The CG-animated film is being produced at Sparx Animation Studios, SAS, a Paris-based leader in key-frame CG-animation. Set for an October 24, 2008 release, Igor will be distributed by The Weinstein Company (TWC), which has an all-encompassing theatrical and DVD distribution deal including North America as well as representing international rights. TWC secured film distribution for most foreign territories at last year’s Cannes Film Festival and American Film Market, as well as the recent European Film Market in Berlin.
