This one is an interesting case, as the younger brother (Park Yang-geun) seems to have done much more work than the other. The comparison is very noticeable in his relatively small number of films on the HKMDB, but even in his exclusively Korean films it's very imbalanced.
They actually show up in quite a few films together, including all the ones on HKMDB, which is nice to see. But it was actually a bit of a pain when it came to IDing as they're almost indistinguishable at times, and when they play more than one role, it really get fun
There is even a small chance that I've mixed them up once or twice (I know the KMDB has), but I'm fairly confident that I've got them all correct....I spent enough time on them He already had a page with one credit on HKMDB for Fire Lord but with no ID. Which is interesting because it just happens to be one of the films where his more prolific brother can't be seen except in the Korean cut. So I've added: his name in Hangul and aliases; a hyperlink between him and his bro's page; and his other films with IDs for all.
