NOT everybody can out-muscle Arnold Schwarzenegger, but Jessica Chastain has done just that over the weekend.
The actress topped the North American box office with her supernatural horror film 'Mama' and the Oscar-nominated Osama bin Laden hunt thriller 'Zero Dark Thirty'.
'Mama' opened well above expectations, with a box office topping $28m. Chastain also held the second spot, with 'Zero Dark Thirty'.
Schwarzenegger's action flick 'The Last Stand' opened with just $6.3m, one of the worst debuts for the brawny 65-year-old star. The film came in 10th.
