This is actually sort of hard when I try to think of it. Like are mini-series included as TV or Movie? For movie themes, do you mean the beginning credits, or the overlying theme that tends to repeat itself throughout the soundtrack? I'm reading too much into it...
TV Show - Lost in Space.
Movie - The Fifth Element Lucia Di Lammermoor/Diva Dance The London Symphony Orchestra, Inva Mulla Tchako
TV show- The Jeffersons, followed in second place by Seinfeld.
I don't really pay attention to movie music that tough to have a favorite song from one.
TV Show - Ironman (for now, always changing)
Movie - Star Wars

-Rush-
Tv - Air Wolf
Movie - Dune (the song at the end,when the credits roll)
�Many things worth doing in the world had been declared impossible before they were done.� Knight Rider on TV and the whole Bram Stoker's Dracula soundtrack for the movies.
Two sorda recent shows I really really like the themes for are "Eureka" and "Dead Like Me".
And for those looking for a good site for a quick listen, http://www.televisiontunes.com/ is one of the best sites. Has some movie themes too.

Rescue Me has the BEST INTRO EVER, it's a T.V show starring Dennis Leary about the firefighters of new york (well, one unit..and their personal/professional struggles post 9/11...) Season one is very intense and every season after that lives up to its expectation. I am surprised it hasn't gained more popularity, Dennis Leary plays an amazing role, the others are pretty great too, aside from the seriousness of 9/11 its comic relief is brilliant, hilarious and raw!
Whale Wars--has smashing pumpkins for their intro--its pretty cool.
Okay movies...hmm, fave theme, hmm 15 years ago I would've said Terminator hands down, I had a BIG crush on Eddie Furlong , lol. There are so many... Neverending Story is one of my all-time faves too Healix ! Arrg, the movie one is just too broad, I can't pick one.....I used to watch movies a lot, but find now I play heroes instead.... Okay for now I'll stick with Terminator cause its etched in my memory from watching it 100+ times, and Neverending story because it is that good.
TV: Peter Gunn (*the* best theme *ever* when you're riding around town in your kitty kar with the top down and the wind whipping through your fur!*)
