Barf. ‘Mamma Mia!’ sets a record of its own.

From USA Today:

There was another record-breaker at theaters this weekend, and it didn’t involve men in bat suits.

Mamma Mia!, the ABBA-inspired film starring Meryl Streep, quietly enjoyed the strongest debut for a musical. If estimates hold, Mamma Mia!’s $27.6 million opening will squeak by Hairspray, which set the mark last year with $27.5 million. It was all part of the busiest weekend ever as more than $258 million poured into the box office, Nielsen EDI reported. The old record was $218 million over the weekend of July 2, 2006.

“Certainly, The Dark Knight tide lifted all boats,” says Jeff Bock of Exhibitor Relations. “But Mamma Mia! pulled off quite a feat, because they did it with very little press.”
