Could easily move up on a second viewing:

Elephant
Femme Fatale
Flight of the Red Balloon
Friday Night
Goodbye, Dragon Inn
I'm Not There
Inland Empire

Lost in Translation
Persepolis
Spider
The Beat That My Heart Skipped
Three Times
To Be and To Have

For the acting:
Before Night Falls
Iris
Michael Clayton
Sexy Beast
The Last Mistress
The Pianist

Can't be as bad as I first thought it was:
Million Dollar Baby

Haven't yet seen:
A Christmas Tale
Cadillac Records
Che (part 2)

and there are surely other contenders I'm neglecting.

Have already made up my mind about:
In Praise of Love (anti-Yank sentiment less annoying on second viewing, if I make a top 100 it'll be in the bottom half)
In the Mood for Love (have seen it three times, probably top ten but not number one)
