Here's my list...

Underground (Emir Kusturica)
Happy Together (Wong Kar-Wai)
Good Men, Good Women (Hou Hsiao-Hsien)
Ulysses Gaze (Theo Angelopoulos)
Close-Up ( Abbas Kiarostami)
La Belle Noiseuse (Jacques Rivette)
Irma Vep (Olivier Assayas)
The Hole (Tsai Ming Liang)
Dead Man (Jim Jarmusch)
The Match Factory Girl (Aki Kaurismaki)

I've also tried to restrict myself to one film per director, though choosing only one from Kiarostami was tough! I haven't seen "Rebels of a Neon God" or "Satantango". The ones that I had a tough time keeping out of this list are -Gabbeh (Makhmalbaf), "Autumn Tale" (Rohmer), "Flowers of Shanghai" (Hou) and "Raise the Red Lantern" (Yimou).
