Early estimates for The Sorcerer's Apprentice's opening day are in, and they could most charitably be called "alarming": The Nicolas Cage fantasy drew $3.7 million on 3,385 screens in the U.S. and Canada, setting some five-day projections below $30 million. That would result in the second straight Disney/Jerry Bruckheimer underperformer after Prince of Persia. Clearly it needed a better iPhone app. [Deadline]
