HBO has secretly made a 4-part documentary on the Woody Allen sexual abuse allegations

• "Allen v. Farrow" will feature new information and never-before-heard interviews.
• It will premiere on HBO on February 21.

On Friday, HBO announced that it will be releasing a four-part documentary that delves into the private life of filmmaker Woody Allen, specifically the allegations of sexual abuse involving his daughter Dylan when she was 7 years old.

Titled, "Allen v. Farrow," the HBO press release says the doc "goes behind decades of sensational headlines to reveal the private story of one of Hollywood's most notorious and public scandals: the accusation of sexual abuse against Woody Allen involving Dylan, his then seven-year-old daughter with Mia Farrow; their subsequent custody trial, the revelation of Allen's relationship with Farrow's daughter, Soon-Yi; and the controversial aftermath in the years that followed."

The first episode will premiere on February 21 at 9 p.m. ET and air the following episodes over the three Sundays that follow.

Directed by Oscar-nominated filmmakers Kirby Dick and Amy Ziering, the made-in-secret docuseries features intimate home video footage, court documents, police evidence, and new investigative work.

It will also feature interviews with Mia Farrow, Dylan Farrow, Ronan Farrow, and others close to the family who are speaking out for the first time.

Insider reached out to Allen's agent for comment about the docuseries but didn't get a response.

Back in the 1980s, Allen was riding high as an acclaimed director and Farrow, who starred often in his movies, was a major star. The two began a relationship and Allen became a father figure to Farrow's kids and the ones they shared. But their relationship turned into a tabloid-crazed downward spiral when Allen announced in a statement in 1992 that he was in a relationship with Farrow's adopted daughter, Soon-Yi Previn. Allen was then 57 and Previn was then 21.

That followed with Farrow accusing Allen of sexually abusing his daughter Dylan, who was 7 at the time.

Allen was investigated by authorities but was never charged with any crimes. He has consistently maintained his innocence. Dylan and Farrow both have publicly maintained that Allen is guilty. The allegations have followed Allen ever since and have led to his films not being released in the US and actors regretting to have worked with him.

Dick and Ziering are no stranger to tackling tough topics. The duo also made the recent documentary "On the Record," which focuses on the sexual assault allegations against hip-hop giant Russell Simmons.
