Harlow has previously been played onscreen by singer Gwen Stefani, who made a brief appearance as the actress in Martin Scorsese's Howard Hughes biopic "The Aviator".
"By Love Reclaimed" is the title of a book by Valerie Franich and Adrian Finkelstein, which attempted to uncover the mystery surrounding Harlow's husband MGM producer Paul Bern's death.
The movie will include the infamous 1932 scandal in which her husband was found shot dead at their Los Angeles home, two months after they married, reports contactmusic.com.
The film is expected to be released in 2015.
