At the moment i can only come up with nine, i really can't think of a tenth.
Bicycle Thieves (Vittorio De Sica 1948)
Blade Runner (Ridley Scott 1982)
The Blue Kite (Tian Zhuangzhuang 1993)
Carnival of Souls (Herk Harvey 1962)
Raise the Red Lantern (Zhang Yimou 1991)
Russian Ark (Aleksandr Sokurov 2002)
The Seventh Seal (Ingmar Bergman 1957)
Star Wars (George Lucas 1977)
2001: A Space Odyssey (Stanley Kubrick 1968)
I know 2001 and Blade Runner are here yet again, but they made such a big impression on me that i had to include them.
My list has pretty much stayed the same for years, i don't really watch films these days very often, not like i did when i was younger. I find it an effort to sit through films now, i have a pile of recently bought criterions including Joan of Arc, Boudu Saved From Drowning, Au Hasard Balthazar sitting around. Maybe these will appear in a list one day, as soon as i actually watch them of course.
