Sylvester Stallone is still flexing those ridiculous muscles of his in 'Bullet to the Head,' an action thriller directed by action vet Walter Hill, and the first poster for the 2013 release has just exploded online! Give it a look after the break!

Any movie that comes out now featuring Stallone, Arnold Schwarzenegger or another well past middle-aged action star is going to be making some age jokes, you can count on it. A few weeks back, the poster for Schwarzenegger's 'The Last Stand' commented that "Retirement is for Sissies." So it's no surprise that the one-sheet for Stallone's latest, courtesy of IGN, is making a funny about the actor's 66 years of age. "Revenge Never Gets Old," it says. 'Cause he's old, you see.

When are they finally going to make an action extravaganza called 'Old Age Home' starring these dudes as a bunch of crotchety seniors who spring into action when terrorists seize their retirement village? Tagline: "We're not too old for this sh-t!" This is money in the bank, people.

'Bullet to the Head,' co-starring Sung Kang, Sarah Shahi, Christian Slater and Jason Momoa, is based on the graphic novel 'Du Plomb Dans La Tete,' and sees Stallone as a hitman who teams with a streetwise cop (Kang) to hunt down the men responsible for killing both of their partners. It opens on February 1.
