Currently in production, Berg's documentary strips away Joplin's rock ‘n’ roll persona.
Berg described Joplin as "an amazing rock icon who paved the way for generations of women to come."
"We have a great producing team coming together to make this film and I hope we make her proud," she said.
Content's Jamie Carmichael said: "I’m a great fan of Janis Joplin, but I don’t think I’d ever heard her real story until now. The incomparable Amy Berg is showing us the woman behind the myth, and the result is fascinating, tragic, amusing and very emotional."
Joplin serves as the narrator for her own life story -- intimate, personal letters she wrote to her family, friends and lovers begin from her childhood until her death -- with the documentary incorporating never-before-seen footage.
It includes Joplin's turn at Monterey Pop in 1967, Woodstock in 1969 and Festival Express in 1970, as well as witness interviews with her family, friends and rock star contemporaries, who are said to paint a new, intimate portrait of the woman and her death.
Her hits included "Cry Baby," "Mercedes Benz" and "Piece of My Heart."
Joplin was 27 years old when she died from a heroin overdose in 1970.
