The director revealed Britney's father Jamie and his team tried to intimidate The New York Times with lawyers in order to shut down the release of this documentary.
For over a decade Justin Timberlake was accused of sexism and misogyny regarding his treatment of former girlfriend Britney Spears. He also would explicitly call her crazy during concerts while playing his "What Goes Around Comes Around" song with a mashup of Gnarls Barkley's "Crazy" and Amy Winehouse's "Rehab" while also calling her names and a "Madonna wannabe" on various occasions. After the release of this documentary, Timberlake issued a public apology on Instagram to both Spears and Janet Jackson (for his handling of the infamous "wardrobe malfunction" at the Super Bowl in 2004).
New York Times journalists Samantha Stark and Liz Day revealed there was a lot they were unable to get into with time constraints, and they wish this could have been a multi-part series in the vein of "OJ Made in America".
At the end of the documentary the members of Britney's family who were requested on-camera interviews with but did not respond or declined are listed. The New York Times reached out to a lot more people than just that list though, including Britney's ex-husbands/boyfriends: Jason Alexander, Kevin Federline, Jason Trawick and Charlie Ebersol. They also spoke with photographers Nigel Dick and reached out to David LaChappelle. There were many people they spoke with on background who did not appear on camera, and then a few people whose on-camera interviews weren't included for time.
Shortly after the release of this documentary Britney's cousin and former assistant Alli Sims gave her first interview in more than a decade stating she carries "a lot of guilt" after she was forced to cut off contact with the singer due to ongoing threats by Spears' father.
