The rock star is a close friend of cinematographer Michael Ninn, who produces porno movies.
According to the New York Post, the guitarist will write and sing two songs, Rise and Catherine for the movie Sacred Sin.
"I’m working with a friend — very simple. I like his work. Michael Ninn is like Spielberg to me: the imagery, the way he makes things look just sensual," confirmed Van Halen.
The movie Sacred Sin will be launched on the market on September 13th 2006.
