The Usual Suspects , that great calm piano intro while the opening credits are rolling.

I must say I love the eeeing sound from the beginning of The Dark Knight, puts a great mood to the movie, and caughts your attention instantly.

Once, was looking for a movie to watch while eating, left it on Once since it just started, and when I heard the song he sang at the beginning I payed full attention.

Here is clip: YouTube - Glen Hansard - "Say It To Me Now" from movie "Once"

The best movie opening theme song has to be Misirlou, from the film "Pulp Fiction".

The opening theme to Ghost Busters.

x2 on Blade and Apocalypse Now

I will add:

Trainspotting with the narration cut with Iggy Pop's "Lust For Life"; and
Reservoir Dogs with the crew sitting around the breakfast table (and Steve Buscemi's riff on tipping) and then "the walk" with "Little Green Bag" by the George Baker Selection - pure magic.

My favorite is "Lock Stock and two Smoking Barrels" with the introduction of the characters done in the coolest way possible!

Apocalypse now, definitely. Such an awesome intro!
