How about:

• The Match Factory Girl (1990) - truly a great film with a very slow pace
• Dogville (2003) - it’s got Nicole Kidman, Lauren Bacall, Chloë Sevigny, and James Caan! I wonder what the sets are like?
• Aguirre, the Wrath of God (1972) - about an exotic river trip. yet so much more.

Judgment at Nuremberg (1961)

I see and raise you: The Wannsee Conference (1984) - about the Nazi meeting in which the “final solution” was decided upon. They just sit around a table talking. Later adapted into Conspiracy (2001). wait these are TV films so maybe they don’t count.

Lost in Translation (2003)

Pretty much everything by Jarmusch. “Hey, want to see a movie about a modern samurai who works for the mafia? It’s got gunfights!” “Sure! Sounds exciting!” Well it is, but not how you think. (Ghost Dog)
