Oscar-winning actress Susan Sarandon (Dead Man Walking) is set for a lead role in Marilyn, a four-hour miniseries about the tragic Hollywood icon to premiere on Lifetime in 2015. Sarandon will play Marilyn Monroe’s mentally ill mother. Based on bestselling book The Secret Life Of Marilyn Monroe by J. Randy Taraborrelli, the biopic will center on Marilyn, who walks red carpets in shimmering gowns while fighting a battle against demons she’s inherited from her mother, whom she loves, hates and wants desperately to save. Marilyn becomes the Face and Voice of an era, yet wants most of all to be someone’s mother and someone’s little girl.

Marilyn was penned by The Kennedys writer Stephen Kronish. Laurie Collyer is set to direct. Jonathan Koch, Steven Michaels, Keri Selig and Kronish executive produce.

Marilyn joins last year’s The Anna Nicole Story and two other Lifetime biopics of female entertainers who faced an untimely death –Aaliyah and Whitney Houston.
