Personally, I'm really fond of Away From Her really doesn't get the attention it deserves- it's a brilliant film about a man who must come to grips with his wife's Alzheimer's disease as she forgets him and falls in love with somebody else.
Watched The Terminal again for the first time in 10+ years and I forgot how good it was. Tom Hanks is great as always.
Hanks is the best. If you tell him to give his worst performance, it'll probably still win an Oscar.
The man does have some serious natural talent.
In no particular order...
3. Office Space
4. Children of Men
5. The Jacket
