For years, the account given by Woody Allen’s then-7-year-old adopted daughter Dylan Farrow in the days following Aug. 4, 1992, when she says he sexually assaulted her, has been central to her case against him.

The specialists who heard the child’s account then and in later years have been divided on whether it was credible or whether it was coerced by her adoptive mother, Mia Farrow. But the public has only heard Dylan, as an adult, recount what she told her mother nearly 30 years ago.

Now Amy Ziering and Kirby Dick’s four-part documentary, “Allen v. Farrow,” which premieres on HBO on Sunday at 9 p.m. Eastern (and streams on HBO Max), will for the first time include video footage of Dylan, recorded by her mother, describing what happened to her just days after she said Mr. Allen molested her.

The film is the latest development in a case that has been debated for nearly 30 years. It made headlines again in 2014 when Mr. Allen received a lifetime achievement award at the Golden Globes — and Dylan Farrow wrote an open letter, posted by the New York Times columnist Nicholas Kristof, recounting her story in detail in response.

Then, in September 2018, New York magazine published a lengthy interview with Soon-Yi Previn, her first extended remarks on her relationship with Mr. Allen, who began to date her mother, Mia, when Ms. Previn was a young girl. Mr. Allen and Ms. Previn began a romantic relationship in 1991, when Ms. Previn was 21.

Mr. Allen has long denied assaulting his daughter and argued that Mia Farrow coached Dylan to say she had been assaulted after discovering that Ms. Previn and Mr. Allen were having an affair.

This timeline highlights important dates and developments in the narrative that has its roots in the 1970s. Based on New York Times articles and other news reports, it is a guide, not a comprehensive accounting, and will be updated periodically.

According to Dylan Farrow, Mr. Allen abused her that day, touching her genitalia. She was 7 at the time. She detailed her accusation in January 2018 on “CBS This Morning”:

DYLAN FARROW: I was taken to a small attic crawl space in my mother’s country house in Connecticut by my father. He instructed me to lay down on my stomach and play with my brother’s toy train that was set up. And he sat behind me in the doorway, and as I played with the toy train, I was sexually assaulted … As a 7-year-old I would say, I would have said he touched my private parts.
