These Are a Few of My Favorite Films
Annie Hall
The Apartment
Arsenic and Old Lace
The Best Years of Our Lives
The Bicycle Thief
Deconstructing Harry
Double Indemnity
Election
La grande illusion
High Noon
Italian for Beginners
The Killing Fields
Kolya
Last Year at Marienbad
Lawrence of Arabia
Life of Brian
Memento
Midnight Cowboy
Mr. Smith Goes to Washington
Network
My Son the Fanatic
Nashville
La Passion de Jeanne d'Arc
Pelle the Conqueror
Pulp Fiction
Raging Bull
Rosemary's Baby
Sholay
Singin in the Rain
Sweet Smell of Success
Training Day
Vertigo
The Winslow Boy
Wonder Boys

UPDATE: I think of Vertigo as Hitch's magnum opus, so I initially didn't include any of his other films on the list. I would add Notorious, North by Northwest and Rebecca this list with the understanding that they are not exactly up to the level set by Vertigo. Of course, I do not love all of the films on this list equally and if I were forced at gunpoint to make a shorter list, it would be:

The Apartment
Double Indemnity
La Passion de Jeanne d'Arc
Last Year at Marienbad
Life of Brian
Vertigo

Ask me a year from now and I will, of course, have a different shortlist.
