Really enjoyed listening to Martinez talk about his thought process behind the Only God Forgives soundtrack in this interview with Slashfilm:
So what ended up happening is kind of this hybrid of several different ideas, one of which was The Day the Earth Stood Still. My favorite score of all time, but even as well as I know it, I can’t imitate it, nor would it have been appropriate. But the idea of something fantastic and something that was otherworldly was the quality we wanted to take from that score. I think at one point we liked the idea of the retro and fifties, but I couldn’t really nail that. So once again I failed in an interesting way.
