Once again Liam Neeson stood up to the January graveyard slate of movies, and once again Liam Neeson took charge. The Grey took top honors this weekend, proving that the combination of Neeson and good, adult action is the way to go when you want to make some decent coin. It wasn’t up to the standards of films like Taken ($24.7m opening weekend in 2009) and Unknown ($21.8m opening weekend in 2011). Considering the R rating, the lack of star power outside of Neeson (Dermot Mulroney isn’t what he used to be, and the wolves themselves don’t have a great agent yet), and Joe Carnahan not being the golden boy when it comes to box office returns, The Grey‘s $20m is still a respectable debut. Neeson isn’t losing clout as quickly as Katherine Heigl, whose One For the Money came in at #3 with $11.7m. That’s slightly lower than expectations, but looking at Heigl’s track record, her opening numbers seem to be whittling down further and further. Since Killers in 2010, Heigl’s opening numbers have progressively gotten smaller and smaller, dropping from $15.8m to $14.5m for Life As We Know It in 2010 and $13m for New Year’s Eve early last month. A change of pace for Heigl might be in order, or, when all else fails, the DVD/Blu-Ray and VOD market is not a bad option to take.
