I don't know exactly when Liam Neeson turned into Hollywood's favorite vengeance machine — the go-to guy for settling scores — but he has definitely arrived with an emotionally gripping performance in the current box-office hit "The Grey." Surely "Taken" in 2009 , with his ex-CIA operative in a relentless and ruthless bid to find his kidnapped daughter, signaled that he had made the A-team. And in 2010, he would actually join a re-imagined "A-Team" as its tactical leader, Hannibal, with all the historic resonance that name implies.
