This one took a bit of back and forth.
He'd already been credited on: 10 Shaolin Disciples; Deadly Shaolin Longfist; Magnificent Natural Fist; The Undertaker In Sohwa Province; and Invincible Obsessed Fighter. But on Invisible he'd been miscredited as Jeon Hak-joon, this wasn't a HKMDB editor's fault though, I remember that the KMDB had got it wrong to begin with. They'd misread the Hanja, which they do more often than you'd think, it's funny how a non-Korean who knows barely any Chinese has to correct it for them
I've also had to change the DOB as well to 1963, I'm not sure where the DOB 22Apr1971 came from, but that would make him about 10yo in his films, which is made all the funnier by the fact he often plays old men with a long grey beard
The only other things to add were his gender and name in Hangul, his credits for Dragon Against Vampire; Eagle Vs. Silver Fox; Shaolin Drunken Monkey; and the cut & paste film Zodiac Power: The Super Master, and of course ID's for all his films (also tagged Gaijin's images on Longfist too).
One image might look familiar, as I mis-ID'd him as Choe Ha-seop in Undertaker (I was about 50/50 at the time), but after getting a version that has less blurred movement I'm confident that it's actually Kim Hak-joon playing more than one role (which he did quite a bit).
