What Are Your Favorite Movie Themes?

I've got to be honest. The pinnacle of Sci Fi movie themes for me comes straight out of the 80's (90's in this case). The Terminator theme is intense and really brings forth the post apocalyptic theme that the movies are about. 

What are your favorite movie themes and why?

I've always loved the open song to the Conan the Barbarian song.

I loved the sound track to Tron. That is part nostalgia. Also the sound track to The Red Planet has been a faavorite of mine. It's done by Graeme Revell.

Stupid movie, great theme.

One of my favorite subjects of all time!

Can't wait to get a few spare minutes and post some favorites in here.

And last but certainly not least, the majestically beautiful masterpiece by composer John Murphy:

I saw this thread and thought it meant movie themes, like under lying message type (themes)

Well Ill list both

My all time favorite movie/book/tv show theme of course is science fiction, but under that genre I love the dystopian, stories, such as Terminator and Mad Max

Ik that Star Trek and Doctor Who are not dystopian but they are obviously war torn and "well used" futures unlike some stories in sci fi

Anyway to the actual question............

T2
