Writer-director Jeffrey Nachmanoff will adapt Neal Stephenson’s cyber sci-fi novel “Snow Crash” for the Kennedy-Marshall Co. and Touchstone Pictures.Marco Brambilla (“Demolition Man”) is attached to direct the project, which has been described as a cross between “Brazil” and “Blade Runner.” In it, a computer virus escapes from the digital to the biological realm. “It is about the disintegration of American society in the information age,” Nachmanoff said. Fresh start Other writers also have written drafts of the script, but Nachmanoff said that he hopes to “start from scratch” in penning his screenplay. “It is a difficult adaptation to say the least,” said Jonathan Zimbert, president of the Kennedy-Marshall Co. “But (Nachmanoff) is extremely passionate and well versed in the material.” Zimbert sees the project as a “big canvas” film and hopes to start production next year. Nachmanoff, who graduated from USC in 1994 and directed the short “The Big Gig,” has several other projects in development. He recently sold his script “Rembrandt’s Shadow” to Par-based Scott Rudin Prods. for low six figures. The project is described as a sexy thriller set in the world of art forgery. He also recently completed the adaptation of “Vulture Fund” for Neufeld/Rehme Prods., also based at Par. The book, by Stephen Frey, is a political thriller set on Wall Street in the vein of “The Firm.” Indie project Nachmanoff also is working on the script “Eurail Pass” for Merv Griffin Prods. along with Tony Griffin, and plans to direct an indie feature from one of his dark comedy scripts. Nachmanoff recently moved to William Morris from UTA. He is repped by Ramses IsHak and Dodie Gold, managers William Blaylock and Paul Canterna, and attorney Fred Gaines.
