The story of Sixties pop group The Mamas and Papas is to be turned into a film.

After two years of negotiations, producer John Davis has clinched a £600,000 deal for the rights to make their story into a full length feature .

Possible names to play Michelle Phillips and the late Cass Elliot include Charlize Theron, Mena Suvari, Denise Richards, Drew Barrymore and Kate Winslet .

Twentieth Century Fox will be making the £30 million biopic of the group who had their first No1 hit with their debut single California Dreamin' .

Insiders say Davis, who has just finished making the thriller Breakers with Gene Hackman and Sigourney Weaver, is putting together a script which will chronicle the group's love affairs, internal squabbling and drugs abuse.

The group broke up in 1967 and Elliot later died of a heart attack in 1974 in London.

Relations between the three surviving members are still said to be 'strained'.

Davis reached agreement with them after they agreed to be credited as executive producers on the movie which is due to go into production next Spring.
