Good vote. Arnold been king of action movies for like a 20 year stretch. Jackie Chan is #1 all time in stunts performed and is an international icon. Sly Stallone is basically the ambassador, leading ensemble cast movies and keeping the aesthetic of an action star afloat through his Rocky and Rambo movies. And Jason Statham can't act in anything except action movies, but they will be watched; he basically took up the torch from the stars of the 80s and 90s.
I ain't mad at none of the other choices, but Arnold, Stallone, Jackie, and Statham are more the epitome of action stars. Tom Cruise is an honorable mention, but because I see him successful in dramatic roles, I say he's more of a well rounded actor than a pure action star even though he got bangers.
