Box office: 'Mama' rules Friday as Schwarzenegger's 'The Last Stand' flops

It was Jessica Chastain vs. Jessica Chastain at the box office on Friday night with her new film "Mama" bowing with a strong $10 million, giving it the edge over the Oscar nominee's other current release, "Zero Dark Thirty," which pulled in another $4.5 million in its second week of wide release. Meanwhile, "The Last Stand," Arnold Schwarzenegger's return to leading man status, bombed.
