Mischa Barton is set to play screen siren Jean Harlow in the biopic By Love Reclaimed.
The former OC star will portray the Red Dust actress in the upcoming film, which is being written by Adrian Finkelstein, reported Variety.
The drama, which will also be co-produced by Adrian, will focus on the 1932 scandal in which MGM producer and Jean's husband Paul Bern was found shot dead in their home in Benedict Canyon - two months after they got married.
Jean - who was one of MGM's leading ladies in the 1930s, with leading men including Clark Gable, Spencer Tracy and William Powell - died in 1937 of kidney failure, aged just 26.
Mischa, who played troubled teenager Marissa Cooper in US drama The OC, has been filming thriller The Hoarder in London. The actress, who turns 28 on January 24, has also wrapped on the indie drama Starcrossed.
