Has the (almost) 60-year-old Liam Neeson, in his second act resurgence, become our most bankable action star? Since the 2008 hit Taken reshaped his image from sensitive character actor to a quietly masculine hero who snaps bones like dried twigs, Neeson has enjoyed a steady stream of #1 box-office smashes: Clash Of The Titans, Unknown, and now The Grey, his wolf-punching existential survival adventure. (The A-Team, from Grey director Joe Carnahan, opened soft, but that was always a dubious act of franchise resuscitation.) At a solid $20 million, The Grey easily won a very winnable weekend, helped along by a number of strong reviews (A.O. Scott’s rave in The New York Times is a great read even by his standards) and some typically weak late-January competition. Really, Katherine Heigl’s drawing power could fairly be deemed substantial, given the stink wafting off One For The Money, a light detective comedy that wasn’t screened for critics and looks like it was shot by precocious raccoons. It opened in third with $11.75 million. Meanwhile, Sam Worthington had his own star power tested, and it turns out that audiences didn’t show up in droves to Avatar and Terminator: Salvation for a chance to see him disappear into another leading role. His profoundly dopey thriller Man On A Ledge limped into fifth with $8.3 million, suggesting that maybe the Worthington magic can only be brought out via green screen.
