In anticipation of the release of Olympus Has Fallen on March 22, Rick Mele over at Ask Men has a post up on the techniques behind fake fighting.
Number 9 on the list is Gun Fu which is the style that Keanu Reeves used in The Matrix. It is a variation on kung fus and uses guns instead of traditional weapons. It is also performed in slow motion. It was first used by John Woo who mixed action movie shootouts with the martial arts but it was The Matrix’s use of the technique that brought Gun Fu into the mainstream.
The entire list and writes for each along with a video clip can be found here.
