Shrek 3 & 4: In a recent sit down with DreamWorks founder Jeffrey Katzenberg, the Sydney Morning Herald got some information out of the producer about the next Shrek films...

"We didn't have the guts to tell anybody when we started out," says one of the most powerful studio bosses in Hollywood. "We have two more chapters to tell. Not unlike Peter Jackson did with The Lord of the Rings. The difference is they did have the guts to make all three of them back-to-back-to-back."

"Thirteen years," says Katzenberg, a small, precise figure with a frantic work ethic. "You think Peter Jackson went at it a long time."
