As you may have noticed, Pixar has come down with a fairly significant case of sequelitis in the last few years. There's 'Toy Story 3' (and maybe 'Toy Story 4'), 'Cars 2' and the upcoming 'Monster's Inc.' prequel, 'Monsters University.' (Sequel, prequel; what's the difference?) Somewhat surprisingly, the second-highest grossing Pixar film ever, 'Finding Nemo,' is not scheduled for continuation. Star Albert Brooks has an idea to change that.
