Perfume: The Story of a Murderer (2006), Hoffman, more importantly Ben Whishaw as Jean-Baptist Grenouille, the murderer. The book is wonderful, and the movie is very good.
For Whom the Bell Tolls, Cooper and Ingrid Bergman are electric together, and it has a great plot.
Tootsie, his/her final speech is hilarious, the entire movie is good.
Butch Cassidy and the Sundance Kid ("Don't they ever get tired, don't they ever eat?")
The Best Years of Our Lives (1946), if you have yet to see this one, it is more than worth watching.
The Others (2001) Nicole Kidman is brilliant; she carries the movie. She should have won an Oscar.
The Hours, Kidman as Virginia Woolf in 1923, Julianne Moore as Laura Brown in 1951, Meryl Streep as Clarissa Vaughan in 2001. It isn't easy, but it is great, and Kidman is again superb.
Dial M for Murder and lust after Grace Kelly.
The Girl With the Dragon Tattoo, with Craig.
One True Thing, Renee Zellweger is the star of this one.
