Dystopia Trailers- Music

I was looking for clips that sounded dramatic and bit dark, and which built up in volume and intensity over time. I found Into the Darkness first. I liked how the song began slowly and with only a few instruments, but more instruments join as the music grew louder.
 I also found the Honors March, the beginning of which I believe we could use for the Surgeon General’s introduction, because I think it would contrast wonderfully with the dark and unnerving beginning to our trailer, where a doctor kills a political dissident.
