Happy Birthday, Alfred Hitchcock!

The best way to celebrate Alfred Hitchcock's birthday -- well, OK, the best way other than actually watching one of his movies -- is to take Anne Thompson's Hitchcock quiz. Don't worry, it's not too challenging. In fact, it's more of a survey than an actual test: You can tell the world what Hitch flick is your fave, which is his most romantic -- and which one has caused the most sleepless nights for you. Plus, you get to answer the burning question that every Hitchcockian must ultimately address: Gary Grant or James Stewart?
