"Hallelujah"

No I am not rejoicing, I am puzzling. I have this semi favorite song that I don't know who the singer is and it drives me crazy. Now I may have stated that wrong since it has been sung by about a million people but I want one particular version. The song is Hallelujah originally by Leonard Cohen. It has been done on American idol by Jason Castro and I liked his version but the version I want is from the movie Shreck. Does anyone know who sang that version? I really want that version of the song because it is so haunting and gives me goose bumps when I hear it. If anyone can help me out here I would appreciate it.
