re: What's your favorite opening scene from a movie ?

Contact

Scene starts out in Earth orbit, as 'current' day radio songs are playing. As the camera pulls back, older and older songs and audio are played. This is to demonstrate that the radio signals we've been putting out for 100 year are ever traveling further out into space. The older the signal, the further away.

If you've got good speakers /headphones, the last thing you'll hear is a Morse code signal for SOS. From the Titanic.

All of modern human history in just under 2 minutes time.
