Yeah, I noticed that one. It is surprisingly well animated for an advert, imo. Going back to my number 28, it was a sort of game-show thing where a bunch of minor celebrities were trapped on an alien planet and had to escape by solving puzzles. Is that enough of a clue?

[Raak] Except it wasn't originally intended as film music. I presume you know it, but some others might not - in its original incarnation it is the opening to Richard Strauss's Also Sprach Zarathustra.

[JLE] Yes, but how many people know it primarily as the Strauss, even the ones who know that's where it came from?

Well, me and Watty for a start... ;-) I've never even watched 2001. Nor, in fact, read the book.

I also knew it was Also Sprach, but since Raak said 'Film music' I replied with the title of the film. On a related note (maybe) it impressed me that 'classical' music was used for that film. Nothing dates a film so much as its soundtrack when a contemporary score is used - even more so when it tries to sound 'futuristic' - so it was a smart decision to choose something timeless, I think.
