Marky Mark's still got it: Mr. Wahlberg's buddy action pic The Other Guys, co-starring Will Ferrell, was tops at the domestic box office Friday, pulling in a cool $13.2 million. If it maintains the same momentum through the weekend, it will stay at No. 1. Step Up 3-D garnered $6.6 million, taking second place on Friday. Meanwhile, Christopher Nolan's mind-bending Inception, starring (among others) Leo DiCaprio and Ellen Page, dropped to third place, earning $5.5 million after three weekends at the top.
