Harry Potter and the Prisoner of Azkaban cast a spell on the weekend box office, conjuring up a magical $92.7 million and setting a new opening record for the wizardly franchise. (I warned ya.) The first two films — 2001's Harry Potter and the Sorcerer's Stone and 2002's Harry Potter and the Chamber of Secrets — opened with $90.3 million and $88.4 million, respectively. Azkaban ranks as the second-best three-day debut on record, behind Spider-Man's $114.8 million haul. After two weeks at the top, Shrek 2 slipped to No. 2 with $37 million for a 19-day total of $313.6 million. The Day After Tomorrow, meanwhile, fell to No. 3 with $28.2 million for a $128.8 million total. The disaster pic is expected to surpass the $135 million mark by, um, the day after tomorrow. (That joke never gets old.)
