I'm huge fan of Danny Elfman's Oingo Boingo and film work. There is a web site dedicated to his film work called Danny Elfman's Music for a Darkened People.
New videos have been posted to the site containing behind the scenes interviews on his work on Spider-Man, Planet of the Apes, Red Dragon, Sleepy Hallow, The Frighteners, Nightmare Before Christmas, Batman, and Batman Returns. The site also has links to clips of unreleased music.
If you are fan of Elman's work, or interested in the process of scoring for film you owe it to yourself to checkout these videos.
I've embedded the video for Spiderman below. To see all the videos, visit http://elfman.filmmusic.com/media.html.
