Martial artists who act vs. actors who fight
Is it just me, or is anyone else completely sick of American actors who learn a few punches and blocks starring in action movies. A perfect example of this was Daredevil. Affleck and Garner knew their moves well enough, but they had none of the speed that makes an action sequence exciting. In the time Affleck threw one punch, a circa 1980 Jackie Chan would have blocked the punch, landed 2 punches and a kick, stolen his wallet, and used the money to buy a 6 course meal and a pint of wine.
But I suppose that kind of work requires dedication, something the likes of Seann William Scott isn't willing to endure.
