Movie music Help PLEASE!?

In some movies there is a type of...I don't know what you call it...Oprah? Orchestra? But it is at the end of Star Wars Episode 1 when Darth Maul, Obi-Wan and Qui-Gon are fighting and something like the music at the end of the The Incredible Hulk trailer ( http://www.apple.com/trailers/universal/theincrediblehulk/large.html ) Does anyone know where I can get this music?
