CHATSWORTH, Calif. — High-end feature production company Ninn Worx is having a blockbuster month. Helmed by film auteur Michael Ninn, the company has arguably scored the biggest coup in the crossover from rock to porn — two original songs from guitar icon Eddie Van Halen for Ninn’s movie “Sacred Sin.”

While much has been made of the close relationship between porn and rap, having the Rock n’ Roll Hall of Famer Van Halen create two original musical pieces represents the highest-profile collaboration of the mainstream music industry and adult.

Van Halen’s two tracks are “Rise” and “Catherine,” a remix inspired by Ninn’s 2005 movie of the same name.

Ninn Worx also has released a preview site to promote “Sacred Sin,” which it calls a dark romance feature.” The site features a variety of video clips, “making of” vignettes, two full movie trailers, video clips and MP3s starring Van Halen performing his two songs, high-resolution photographs and an in-depth introduction to contract star Heather Vuur.

Vuur, the January 2006 Penthouse Pet of the Month, contacted Ninn Worx about an exclusive contract with the studio. “Sacred Sin” is Vuur’s adult film debut.

“Anyone can see the impressiveness of [Heather’s] looks, but what really captivated me was her enthusiasm, intelligence, life experiences and her ability with a script to bring my thoughts and visions to life,” Ninn said. “I’ve been around long enough to know this to be a rare talent.”

Ninn Worx will release “Sacred Sin,” shot in hi-def, on Sept. 13, distributed by Red Light District. The two-disc set will contain music videos for both Van Halen songs.
