Oscar-nominated films I haven't seen:
- Apocalypto
- Blood Diamond
- Borat
- Click
- The Curse of the Golden Flower (Man cheng jin dai huang jin jia)
- Flags of Our Fathers
- The Good German
- The Good Shepherd
- Half-Nelson
- Happy Feet
- An Inconvenient Truth
- The Last King of Scotland
- Little Children
- Marie Antoinette
- Monster House
- Venus
(Plus almost all of the documentaries, short films, and the foreign language category--I am excluding them from my count because they were either not distributed, or never played at a theater near me.)
20 versus 16. I've seen more than I haven't. And in my defense, some of the ones I missed were Click, Marie Antoinette, and Monster House. Not Academy Award winners by any stretch of the imagination.
What's your count?
