Whenever February rolls around, there are always any number of romantic, lovey-dovey movies that girlfriends will drag their boyfriends to. While 2013 looks to be no different (i.e. Safe Haven, Beautiful Creatures), the month kicks off with the explosive, dude-centric Bullet to the Head. Sylvester Stallone stars as a hitman who reluctantly joins forces with a cop (Sung Kang) to go after the man who killed both their partners. Today, a new poster has debuted that proves revenge never gets old. Neither does Sylvester Stallone, apparently, since the action star is still in peak physical condition, as you can see in the one-sheet for director Walter Hill's action-thriller.
