Have been going up the wall trying to restrict myself to ten. Extremely difficult because some of directors I like (Rohmer, Wenders) have been prolific in the 80s and turned out very good films. This is also the decade when Indian cinema, post Ray and Ghatak, has produced some of the most exciting work.

1. Sans Soleil - Chris Marker
2. Ashik Kerib - Sergei Parajanov 
3. Man of Iron - Andrzej Wajda 
4. A Notebook on Clothes and Cities - Wim Wenders 
5. Time of the Gypsies - Emir Kusturica 
6. The Green Ray - Eric Rohmer 
7. Vagabond - Agnes Varda 
8. Fitzcarraldo - Werner Herzog 
9. Om Dar-b-Dar - Kamal Swaroop 
10. A City of Sadness - Hou Hiao-Hsien

Amma Ariyan - John Abraham

Siddeshwari - Mani Kaul
Tangos, the Exile of Gardel - Fernando Solanas

The Yellow Earth - Chen Kaige
Do You remember Dolly Bell? - Emir Kusturica
