When it comes to Action Movie Actors, I consider Arnold Schwarzenegger to be the Number 1 Greatest.

No, but something a comedian who I cant remember said is very true, you gotta respect him because he left his hometown in Austria with nothing but his pecs and ended up not only becoming a freeking billionaire and one of biggest action stars ever but also the guv of an entire state, all while sounding like a drunk down syndromed baby with a mouth full of peanut butter.

He isn't a great actor. However his athletic background, his year of military experience, and his self-confidence all combined to give the experience he needed to be a good performer that could act well enough that he could be a good entertainer.
