"It's not something I can really talk about in detail," Michelle Phillips tells Billboard.com, "but I will say this -- it will happen, and it will happen in a good way.
The gears are all churning."
Phillips -- whose 1986 memoir "California Dreamin': The True Story of the Mamas and the Papas" provides some of the basis for the film -- confirms that "we have an A-list writer and we do have a studio." The writer is reportedly Marshall Brickman, a onetime folk singer and friend of the band whose credits include Woody Allen's "Manhattan," "Annie Hall" and "Sleeper" as well as the Broadway hit "Jersey Boys.
"
Phillips did say that the success of movie biopics such as "Ray" and "Walk the Line" have helped generate more heat for the Mamas and the Papas story in Hollywood.
"Before that, studios were not interested in stories about musicians," she says. "I mean, this i not a musical, per se; this is not a musical like 'Dreamgirls' where people are gonna break out into songs.
This is the story of the Mamas and the Papas -- and, of course, there'll be a lot of music in it.
