He composes the music for ALL of Gus van Sant's films.
However, we do have to insert a small note of caution. Danny's involvement has still not been officially announced. He's merely turned up on IMDb's cast and crew list for the Death Note film. That might just be an extrapolation from the knowledge that Gus van Sant is strongly tipped to take over as director.
Even if you think you don't any of Danny Elfman's music, you do. He's been involved in some of the biggest movies and TV shows over the past three decades. The Simpsons, Good Will Hunting, Ghostbusters II, the 1989 Batman movies, Nightmare Before Christmas, Edward Scissorhands, Epic, Alice in Wonderland, Milk, The Corpse Bride... need I go on?
In fact, have a gander at this lot and tell me from where you know him. I guarantee there will be something!
He's long since been my composer of choice for this project anyway. So I'm thrilled with the strong possibility that Danny Elfman is now on board with Death Note.
