And if anyone says “I’m Norwegian and my favourite foreign-language film is Die Hard 2: Die Harder”, then that forumite gets a free ticket with Yippee-Ki-Yay Airlines. One way, of course. Should go without saying.
Like Jello said, Downfall. Dead Snow was fun. I thought Mesrine was pretty good. Zwartboek was good. I remember really liking Ran after it got going, but it's been almost 40 years ago that I saw it.
My best memory of watching Ran was that I was still living with my parents. I waited to put it in the VCR when they went to bed. My dad came back down and started talking to me about something and then was going to head back to bed, but that's when it started getting good. He stayed up and watched the whole movie with me, really enjoyed it
I used to really like the caro/jeunet stuff (delicatessen, city of lost children, etc), but haven't seen any of them in well over a decade and I'm not sure they would still do it for me. Delicatessen would still be the best I think. Cinema Paradiso was also a favorite way back in high school
Kagemusha, Rashomon, Akira, Urotsukidōji. Urotsukidōji is like Salo, everybody should see it for the sake of realizing how a movie can be utterly horrifying without being a horror film.
