Despite his best intentions, moviegoer Brad Schuyler failed to make his snack supply last beyond the opening credits of Monsters, Inc. Monday. 'The Harry Potter trailer came on, and I guess I just got excited,' said Schuyler, 26, who took his last bite as the words 'Written By Dan Gerson' appeared on the screen. 'Maybe I should have bought more than a box of Sno-Caps and a 32-ounce Coke, but the stuff costs so much.' Next time he sees a film, Schuyler said he will not start eating until the studio logo appears.
