Arnold Schwarzenegger. Bruce Willis. Sylvester Stallone. Three of the biggest action stars ever, they dominated the box office throughout the ‘80s and early ‘90s while leading a parade of testosterone-laden tough guys that included the likes of Harrison Ford, Steven Seagal, Jean Claude Van Damme and even, on occasion, Nicolas Cage.

Some are still working regularly -- perhaps more than they should be -- but no one’s getting any younger. So who are the bright new faces on the action scene? Who out there can convince us as he wields a gun, a blade, or a shoulder-launched cruise missile? Here are eight possible contenders for the action crown -- let’s see who mans up and takes the honors in the months or years ahead.
