It's the biggest Tuesday ever," said Mike Vollman, spokesman for Paramount, which released "Transformers" along with fellow Viacom Inc. unit DreamWorks. "It's playing very broadly. It's the kind of summer movie that's drawing families and we're very excited for its progress going into the rest of the weekend."

The sci-fi adventure "Transformers" had an unprecedented Tuesday haul of $27.4 million in its official debut, beating a record of $15.7 million set last year by "Pirates of the Caribbean: Dead Man's Chest."
