Okay, not strictly "movie scores" - but I find most things by Two Steps from Hell to be epicly sublime... and they do quite a bit of music for movie trailers. Such as this from an official Star Trek trailer: https://www.youtube.com/watch?v=XoiyW23opQk From Anna Karenina trailer: https://www.youtube.com/watch?v=sKB679OI37s From Pacific Rim: https://www.youtube.com/watch?v=bptrpjqXD9s They do some for computer games as well, and some non-movie stuff... of which I think this is the most epic I have heard from them...
