Sweet movie intros

Opening credits
Opening sequences
Whatever you'd like to call them

I saw this topic on the message boards over at popsyndicate
I thought I would show my thoughts here and ask if anyone has any they would like to share here as well!

I love these three intros - two from films from last year, one from a film from 1974


The first is 2009's Watchmen
sorry, I cannot embed this one

Then 2009's Zombieland


Then Enzo Castellari's 1974 film Street Law


see a trend?
