A very easy one this time since as far as I can tell this fellow has this one and only credit. It could be that he's in other films as a stunt man or under a different name (as he does look kinda familiar), but nothing that I'm confident on. I had to create him a page. but with very little to enter into the basic info, just his gender, country and his name in Hangul.
