I've listed the movies in order of the earliest production, i.e. which he worked on first rather than release date. I'm happy to help provide info on any of Won Jin's movies listed. It was hard to track them down, but hopefully now others won't struggle as much as I did to find the work of this underrated martial arts god. There could still be more out there, if you find any let me know.
Cheers.
