1. In 'Psycho', where the guy is creeping up the stairs to check out the mother's bedroom, and the camera switches to an overhead view and then - out of nowhere - she rushes out knife in hand. Shits me up just thinking about it.
2. For that amazing shot in 'Frenzy' where you realise that the neck-tie killer is about to strike again and the camera just moves out of the door, down the stairs and across the market square making your realise how alone the girl is.
3. 'Vertigo', for totally flummoxing it's audience with a twist out of nowhere.
4. 'Stage fright', for being one of the most forward thinking and funny films of it's period.
5. 'Rear window'. For being the utterly perfect mix of timeless, romantic, funny and vaguely dark.
6. How great his trailers were, like this one for 'The Birds': http://www.imdb.com/video/screenplay/vi1056113433/
7. 'Notorious', for being both totally far fetched and believable at the same time and confusing you even past the final credits.
8. 'The 39 Steps', for loads of reasons but ultimately being the best 'chase' film ever.
9. For the scene in 'Rear Window' where he told both under-performing extras to make sure they got the mattress inside when it started raining. He told them to use different windows though, knowing that they'd panic and start fighting; exactly what the scene needed. He supposedly sat there laughing and the scene is in the finished film.
10. 'To catch a thief', for having the most beautiful background locations ever.
I've missed out about 100 others. I like Hitchcock, a lot. Do you?
(Psycho is being remastered and re-released at the BFI next month btw)
