In the second episode of the bombshell series — which premiered on Sunday, February 28 — Farrow opened up about when she adopted her daughter Soon-Yi Previn, who went on to marry the famed director in 1997, five years after his split from Farrow.
Farrow, who adopted Soon-Yi when she was around seven, explained that she had trouble bonding with her daughter since she brought her into the family at a later age.
The actress, 76, was a mother to seven before she met the Annie Hall director, 85. She and ex-husband André Previn shared twins Matthew and Sascha, Lark Song, Fletcher and Summer "Daisy" Song, as well as Soon-Yi and Moses Farrow, whom Allen later adopted. Farrow and Allen — who began dating in 1980 — also adopted daughter Dylan and share biological child, Ronan Farrow.
Farrow claimed she worked "very hard over many years" to create a bond with Soon-Yi, as she would take her onto her film sets "because I did not want her to be separated from me, even overnight." Farrow figured that Soon-Yi would eventually "understand that I'm going to be there for her as long as she lives."
Farrow admitted that she "encouraged" Allen to work on creating a relationship with Soon-Yi. "He took the little ones shopping and bought them airplanes and magic tricks," Farrow recalled in the show. "He started bringing all of them to basketball games. I really encouraged him to go with Soon-Yi, too, because she was really shy."
Farrow claimed Allen's relationship with her adopted daughter began when Soon-Yi was still in high school, while Allen alleged their relationship began after Soon-Yi's first semester at college in December 1991.
"I love her so much and I didn't ever blame her, you know, because she was just a little kid when he came into the family," Farrow noted of Allen and Soon-Yi's romance.
"She was a little girl. We were family and he was in my home as my partner and as such he had responsibilities," Farrow added. "You don't get to have sex with my children. That isn't part of the deal."
In the second episode of the shocking docuseries, Farrow also alleged that her and former flame Allen began having issues in their relationship during the time that Farrow was struggling to bond with Soon-Yi.
"After a while, it didn't matter what I was or what I thought, I was there to serve him it felt like," the Husbands and Wives actress claimed. "I went into that role and tried to be the best version of what he wanted. Funny but not too funny, answering but not too talkative."
She continued: "For years he had said how lucky I was to work for him because [he'd say], 'Actors your age, they're dime a dozen. I could pick up the phone now, I can replace you in less than 2 minutes.'
"It was Woody's world and it was very controlled," Farrow added.
The HBO docuseries used excerpts from Allen's autobiography Apropos of Nothing, in which he detailed how his romance with Soon- Yi, now 50, began. "I did take her to a game," Allen recalled in his audiobook.
"As we chatted at the game, I found that I was enjoying her company more than I should have. Cut to some time later, I'm shooting Husbands and Wives, Soon-Yi comes in from college and I screen The Seventh Seal," he said. "Bergman's film ends and we're alone in my screening room, and quite smoothly, if I do say so myself, I lean in and kiss her."
Allen co-starred in 1991's Husbands and Wives with Farrow. The former couple — who collaborated on 13 films — debuted the film in 1992 after their split.
He admitted that he and Soon-Yi — who now share two daughters — thought they "could have our little fling" and "keep it a secret" because "Soon-Yi wasn't living at home and I lived alone like a bachelor." Allen felt Farrow's adopted daughter would eventually go on to have a conventional relationship with someone in college; however, he "didn't realize how attached to one another we'd already grown."
Farrow eventually moved her kids out of New York City to a home in Connecticut and allowed Allen to visit the children once a week.
In the docuseries, their daughter Dylan, whom Farrow adopted in the early stages of her relationship with Allen, went into detail about her accusations of sexual assault against Allen. Dylan's accusations against the director were first brought to light when Farrow and Allen, who was never charged, split in 1992.
Allen and Soon-Yi have since slammed the HBO docuseries, calling it a "hatchet job riddled with falsehoods."
New episodes of Allen v. Farrow air every Sunday at 9 p.m. ET on HBO and are available to stream on HBO Max.
