I made a new discovery at the Busan Cinematheque today - they have an archive of thousands of DVDs that you can watch there on small screens with headphones for free. It definitely doesn’t make for the best viewing experience (only hardcore cinephiles will probably want to bother), but it’s the only way to get access to such a vast collection of rare titles in Busan. I glanced at the selection for a few minutes, and it’s pretty impressive - lots of older, artsier stuff made by well-regarded filmmakers.
