In a thread that started with Babylon 5, I can’t believe nobody’s mentioned Doictor Who, which has had 7 or 8 versions (not counting the TV movie and the spin-off radio shows and web animations).
And what a great theme it was, too. It started with Ron Grainer’s spooky early electronica, which was simpe, creepy and effective. Then when they changed actors for the Doctor, they added the new actor’s face to the opening and added some flashes and added a weird sweeping flourish to the theme, which frankly made it sound overworked. When the third actor came in, they redid the opening in color (with the new actors face) but kept the theme - except at least one episode in this run had a completely different theme, with the same tune played on a bouncy harpsichord, that sounded completely stupid. When the fourth Doctor (Tom Baker, the one you all know) came in, they redid the titles again, with the new face - but this time with entirely different graphics as well (a tunnel effect instead of a kaleidescope pattern). I think they might have changed the orchestration at the beginning of the theme slightly, but I’m not sure. It’s possible the MP3 I have just fades in at a different point.
So that’s 3 or 4 themes now (one of which was only used for a few episodes) and 4 sets of graphics. Then when the fifrth Doctor came in, they redid the whole thing from scratch, with starscape graphics and a theme with a faster tempo and electric guitars. It’s fairly cool (especially considering it was recorded in the 80’s) but is thinner and lacks the atmosphere of the original.
The sixth Doctor’s theme was like the second’s - they took the theme from the previous season and added some flourishes. The starscape got a blurry-line tunnel effect and the theme song got some spangles, but it’s essentially the same. For the sixth Doctor’s last season (the Trial of a Timelord), though, they kept the graphic but recorded a new theme. It’s got a slightly slower beat and sounds much darker. It’s more modern than the original theme but every bit as spooky. The stories themselves weren’t great, but Trial gets my vote for the best theme.
What are we at now - 6 or 7 themes (depending if Tom Baker’s was different or not, I can’t remember) and 6 sets of graphics. The seventh Doctor again got a complete revamp, with glitzy computer graphics (which, frankly, look like they’re trying too hard) and a synth-and-guitars theme that was nearly as cheesy as the harpsicord. What a horrible leap backwards electronica’d taken.
And then it got cancelled.
The TV movie, years later, had an orchestra, which was pretty interesting but a little plodding. And I’ve heard there were other versions for audio books, radio dramss, and the like, but I don’t know them.
So there you have it - 30 years of different themes for just one show.
