Hana-Bi by Takeshi Kitano
Smultronstället by Ingmar Bergman
Ugetsu Monogatari by Kenji Mizoguchi
The third man by Carol Reed
Ran by Akira Kurosawa
This is my top 5 for the present moment, even though I have many other movies I'd like to put in the list. But since you probably ignore what they are, it would be kinda pointless to make a loger list of titles...
Iguana, interesting choice
