Jessica Chastain easily outmuscled Arnold Schwarzenegger and Mark Wahlberg over the weekend, topping the box office with both her horror film “Mama” and the Osama bin Laden hunt thriller “Zero Dark Thirty.”

“Mama” opened well above expectations $28.1 million, according to studio estimates Sunday. Chastain also held the second spot with “Zero Dark Thirty,” for which she’s nominated for the best actress Oscar.

Schwarzenegger’s action flick “The Last Stand” opened with just $6.3 million, one of the worst debuts for the 65-year-old star, and Wahlberg’s “Broken City” didn’t fare much better.
