I would have to go with:
Withnail and I - Bar none the best comedy, and perhaps best tragedy of the last 30 years.
Hard-Boiled: The greatest action movie of all time. Chow Yun Fat trasncended to the multi-verse while firing a pistol in each hand.
California Split - This movie just gets life, man.
1. Breakfast at Tiffany's (how come the movie's actually better than the book?)
2. Streetcar named "Desire" (with Viviene Leigh and Marlon Brando)
3. The Dressmaker (same as with "Breakfast at Tiffany's", the book is fine, but the movie rocks)
