Alfred Hitchcock's movies

Off late, I started watching a few of Alfred Hichcock's movies. I would say "Dial M For Murder" is the best detective movie I have ever seen. I have started liking the subtleness of the characters and the succinct dialogs. Especially when Inspector Hubbard asks Margot, "Madam, you are saying that you didn't see the killer. But you confirm that you don't know the killer. How is that so?." (Pardon me for not being verbatim :-)

These are the list of movies I have watched so far:

1. The Paradine Case
2. Dial M For Murder
3. Spell Bound
4. Notorious

I bet its worth giving a try to watch Alfred Hitchcock's movies :-)
