Did you mean Jeff Wayne's War of the Worlds, or the film sound tracks? I'm not so familiar on the latter, but the former is the best! The only vaguely "prog" album my old flatmate could stomach.
I was once very bored, and decided to try watching a film with the sound off with War of the Worlds on in the background to see if it at all synced up (as Wizard of OZ and Dark Side of the Moon) are meant to. Looking through my then flatmate's DVD collection, the film that seemed to have the same running time was Big Trouble in Little China! I commented on it live to a forum I used to be on. It very rarely did match up - but it was a fun night!
