What Movies Would You Kill to See?

What Movies You (metaphorically) Kill to See? No, not the movies that you just haven't see yet, not the ones on the bottom of your Netflix queue. The movies you just can't get ahold of, and no one's going to be playing them on a big screen anytime soon. (and, no, not the ones Criterion is going to release next month either).

Here's a shot at mine (I haven't seen them, so I can't comment on them!):

1. Humanity and Paper Balloons (Sadao Yamanaka, 1937)
2. Killer of Sheep (Charles Burnett, 1977)
3. Une chambre en ville (Jacques Demy, 1982)
4. The Asthenic Syndrome (Kira Muratova, 1989)
5. Metaphor (King Vidor, 1980)
6. Milestones (Robert Kramer, 1975)
7. Tokyo Twilight (Yasujiro Ozu, 1957)
8. Early Spring (Yasujiro Ozu, 1956)
9. History Lessons (Straub / Huillet, 1973)
10. Jeanne Dielman (Chantal Akerman, 1976)
