The announcement was made earlier to day at CinemaCon in Las Vegas, though the names of any screenwriter or director were not forthcoming.
Little is known about the film’s plot other than it will be a prequel and will show how scare engineers Mike and Sully became friends. Billy Crystal and John Goodman will be back to supply their voices to the two characters. Steve Buscemi will also be back to play their nemesis Randall Boggs.
The film is currently scheduled for a late 2012 release.
