Fable Works and Sparx Animation Studios ("Igor") will produce the computer-animated feature "Cereal Heroes" says The Hollywood Reporter.

David Meinstein ("Portal") is writing the screenplay, which revolves around cartoon cereal box-mascots who are mistakenly brought to life when a plan to replace the world's fallen superheroes with characters from comic books goes awry.

They soon find themselves on the run in an unfamiliar world that only they can save from destruction.

Stephen Silver ("Kim Possible") is designing the characters. A film release in 2010 is planned.
