Update: This is a fake but a good one all the same.
The Director of the film, Joseph Kosinski told MTV recently why he chose the band to work on the soundtrack:
I’m a huge electronic-music fan. This is a film where there was a lot of interest from different electronic bands that I follow to work on the film. I felt it was important, just as the first film was so forward-thinking visually and Wendy Carlos’ music was so innovative, I felt we had to do the same thing here. So rather than going with a traditional film composer, I wanted to try something fresh and different. I set up a meeting with Daft Punk. We met for pancakes at the 101 Coffee Shop in L.A. one morning. These guys take “Tron” very seriously. Obviously, “Tron” was a huge influence on them. It was almost like they were interviewing me to make sure that I was going to hold up to the “Tron” legacy. But the more we talked, we realized that creatively, we were totally synced up. I’ve been working on it with them for over a year and a half. I don’t know of a movie where you’re working on the soundtrack months before you start filming.
