Mia Farrow's "great regret" is bringing Woody Allen into her family.
The 76-year-old actress understands why no one believed her daughter Dylan's allegations that the director molested her when she was just seven years old because she "admired" and "loved" him just as much as his fans did and she admitted she blames herself for what was alleged to have happened.
Speaking on the first episode of HBO docuseries 'Allen v. Farrow', Mia said: "That's the great regret of my life, that I wasn't perceptive enough. It's my fault.
"I brought this guy into my family. There's nothing I can do to take that away.
"I get why people can't believe it because who on Earth could believe that of Woody Allen? I couldn't believe it. I couldn't believe it. Everybody admired Woody so much, loved him, and I did too."
Mia already had seven children before meeting the 'Annie Hall' director - who has always denied the allegations and never been charged - but initially kept her life as a mother separate from their relationship because the filmmaker, now 85, said he didn't want to be a father.
But in time, Allen "gradually" warmed to her children and in particular her adopted son Moses and eventually agreed to have a child, but after the 'Rosemary's Baby' star failed to get pregnant, she brought up the possibility of adoption.
Mia recalled: "He said if I wanted to do that that it wouldn't ruin the relationship but that he wanted nothing to do with it. I thought, 'That's fair.'
"He knew the kind of children that I adopted that were all from different countries with different needs.
"He said, 'I might be more kindly predisposed if it was a little blonde girl.' I thought if he cares about that I should try to find a little girl like that and maybe he'll love her. I eventually ended up with a little blonde girl and that was baby Dylan."
