Lifetime is readying another biopic of a female showbiz star whose life was tragically cut short — Hollywood icon Marilyn Monroe. Tentatively titled Marilyn, the film hails from Asylum Entertainment, the company behind The Kennedys miniseries, which also touched upon Marilyn’s story. (The bombshell, whose life was intertwined with those of John F. Kennedy and Robert Kennedy, was played in the mini by Charlotte Sullivan.) Marilyn was penned by The Kennedys writer Stephen Kronish based on the book The Secret Life Of Marilyn Monroe by J. Randy Taraborrelli. Laurie Collyer is set to direct. Jonathan Koch, Steven Michaels, Keri Selig and Kronish executive produce. Asylum, whose Kennedys miniseries aired on ReelzChannel after getting dropped at the last minute by Lifetime sibling History, recently did another biopic for Lifetime, Ring Of Fire, about the life of June Carter Cash and Johnny Cash. At Lifetime, Marilyn joins last year’s The Anna Nicole Story and two other biopics of female entertainers who faced an untimely death —Aaliyah and Whitney Houston — that are in production.
