San Francisco, movies...?

I know, talking about movies is not that interesting right? Well, I can't do anything about it. I love movies and here I am figuring that while in San Francisco I might as well visit some cool place where I know they shot a famous film. Yeah, I am going to San Francisco!!! I already did this once: in Rome. I visited Via Margutta 51, the address where Joe Bradely (Gregory Peck) is located in Roman Holiday. It was really a lucky day because I was visiting my sister in Rome and although the courtyard of that building is usually closed it was open that day. Living, physically, what you only saw on the big screen is of incredible power.

So can you tell me some good movies shot in San Francisco that are depicting really cool places to visit, memorable spots...?

For now I have just spotted those:

• The Birds (not seen - shame on me)
• Vertigo
• Sister Act
• Serendipity
• Sweet November
• Raiders of the lost ark
• Play it again, Sam
• Mrs Doubtfire
• Nine months

Before I go on quoting all the 90s movies I recall being shot in S.F. and more importantly before I go back to watch Hugh's Grant dull hair in "Ninte months", do you have some good suggestion on what to watch?
