Katzenberg Divulges the "Shrek 3" Plot
... the King says to them, "If you can find the heir to the throne and bring him back, the Kingdom will be in good hands, then you can return to swamp and live your lives." Which is what they want to do. Shrek, Donkey and Puss go to the far side of the Kingdom of Far, Far Away where young "Artie", who is the nephew of Queen Lilian, is about to graduate school. Artie turns out to be young King Arthur and Shrek and Donkey and Puss have to convince this extremely rebellious young man, who's being voiced by Justin Timberlake, to come back and assume the throne." "Shrek 3" opens May 2007.
