If you haven't checked out the Guardian's very fun infographics on Hitchcock's oeuvre -- just in time for his birthday today! -- you should do that. This is my favorite part because I think it's just brilliant with the top tens from film fans, critics, and the general public overlapping and disagreeing.
What's more I think it's absolutely accurate in its overlaps and exclusions for all three groups with the possible exception of The Birds not finding its way to the "film fan's top ten". But this can't have been easy to flip around with a stuck landing.
As for myself I have six total favorites: Notorious, Psycho, Rear Window, Rope, Shadow of a Doubt, and Vertigo. But the rest of his output fights over my leftover affections and wins and loses depending on my moods and depending on which part of the movie we're talking about.
Happy 114th Birthday, Hitchcock!
