Hypothetical question for yah: in a fight between action star Sylvester Stallone, and the guy who played 'Conan the Barbarian' and King of the Dothraki in 'Game of Thrones,' who would win? We might have an answer to this not-so-age-old question in the first clip from 'Bullet to the Head.'

Just as Arnold Schwarzenegger is trying to prove he still has the action movie touch, so too is Sly Stallone with this post-'Expendables 2' gig 'Bullet to the Head.' While the movie posters tease the star's age with tag lines like "Revenge Never Gets Old," (he turns 67 in July, by the way) his performance in a bathroom brawl with 'Bullet to the Head' co-star Jason Momoa proves he's still as agile as ever.

IGN debuted the first clip from the action movie, previewing Stallone's portrayal of James Bonomo, a New Orlean's hitman whose partner is murdered by Momoa's character. His need for revenge leads him to partner up with a NYC cop to take down the responsible party.
