Pawlikowski's top 10 for the last Sight and Sound poll:

Ashes and Diamonds
A Blonde in Love
Cul de Sac
Days of Heaven
La Dolce Vita
Do you Remember Dolly Bell?
Mirror
One Flew over the Cuckoo's Nest
Some Like it Hot
Taxi Driver

of these Dolly Bell may be least famous but i would certainly recommend it.
