According to studio estimates Sunday, “Mama” earned $28.1 million. Chastain held the top two spots with both “Mama” and the Osama bin Laden manhunt drama “Zero Dark Thirty,” for which she’s nominated by the best actress Oscar. In its second week of wide release, “Zero Dark Thirty” took in $17.6 million.

Schwarzenegger’s post-governorship comeback got off to a poor start. His action flick “The Last Stand” opened with just $6.3 million, one of the worst debuts for the brawny 65-year-old star.

The Mark Wahlberg, Russell Crowe New York crime film “Broken City” didn’t fare much better. It premiered with $9.1 million.
