CNNMoney: The disaster film starring Dwayne “The Rock” Johnson took in an estimated $53.2 million in its U.S. debut. This total gives “San Andreas” the top spot for the weekend and is roughly $13 million more than what most box office analysts were expecting. “After the weak debut of ‘Tomorrowland’ last weekend, the market was definitely wide open for a breakout,” said Phil Contrino, chief box office analyst at BoxOffice.com. For Johnson, “San Andreas” is the biggest opening of the actor’s career for a film in which he played the leading role.
