Which movies have the best opening 2 - 3 minutes?

Fanny and Alexander (the sound of the Schubert quartet and the face of the little boy full screen playing with his puppet theater quietly) Haunting and draws you into the movie.

The Sound of Music (Julie Andrews turning round and round at the top of the mountains and then singing "the hills are alive...")

Saving Private Ryan (though the opening sequence is longer than 3 minutes) 

Let's make a list.
