I'm using soundtracks from different films, since this film isn't going to be widely distributed or sold, I shouldn't have to worry about copyright issues or anything. I've found a lot of usable stuff from the Harry Potter soundtracks, Lord of the Rings soundtracks, Star Wars II and III and, oddly enough, Batman Begins. I'm not looking for big blaring themes, so much as I just want eerie backing music, sort of like the creepy violins during Quint's U.S.S. Indianapolis speech in "Jaws".
