HBO might soon have another mega-hit documentary on its hands. On Feb. 21, the network will debut Allen v. Farrow—which examines Dylan Farrow’s sexual-abuse allegations against Woody Allen (which he’s repeatedly denied), the director’s custody battle with former partner Mia Farrow, and his subsequent relationship with Farrow’s adopted daughter Soon-Yi Previn.

The four-part docu-series—from filmmakers Kirby Dick, Amy Ziering, and Amy Herdy—will include exclusive interviews with Mia, Dylan, and Ronan Farrow, prosecutor Frank Maco, and family friend Carly Simon, along with other relatives, experts, and eyewitnesses, Variety reported on Friday. (Ronan Farrow has a development deal with HBO to develop and front investigative specials, but it’s unclear when the first of these projects will debut.) The series will also include home movies and previously unheard audio tapes. “No matter what you think you know,” the docu-series’ newly released trailer promises, “it’s just the top of the iceberg.”

Correction: A previous version of this post stated that Mia Farrow was Woody Allen’s former wife; the two were never married.
