Nowadays, EVERYTHING action related is done using cables & green screen effects. I remember HK action stars use to brag "we don't use" green screens, but now these same people are using them in all their works as actors and as producers. They, of course, always blame it on "casualty/accident insurance"... I've seen big stars w/ at least 2-3 safety cables attached to them, that's really cowardly, compared to the old days... Hypocritical if you ask me...
