In a March 2016 interview in Collider, Jacob Bernstein said that the most challenging aspect of this movie's production was the protracted negotiation with his own father, Carl Bernstein, about his appearance in the film. In the movie itself, Jacob Bernstein also says that his parents' divorce stretched on for years and was a great deal more complicated than most divorces in part because of his father's insistence on negotiating on the content of another movie, the film adaptation of Nora Ephron's roman a clef account of their breakup, Heartburn.
Both Max Bernstein (Nora Ephron and Carl Bernstein's younger son; director Jacob Bernstein's brother) and Nicholas Pileggi (Nora Ephron's widower) declined to appear in the documentary for different reasons. In a New York Magazine interview, Jacob Bernstein explained that both Max Bernstein and Nick Pileggi both felt that the grief they felt at the loss of Ephron was "still too raw for them" to be able to talk about her on camera. Bernstein also said that Max's relationship with their mother had been much more private and personal than his own. Pileggi and Max Bernstein did express support of the making of the documentary in other ways--both have viewed the finished film and attended public events promoting it.
