The People v. O.J. Simpson: American Crime Story has been criticized for not being 100 percent accurate, so ET revisited old interviews with Nicole Brown Simpson's friend Faye Resnick that took place during the trial.
The FX miniseries' portrayal of Resnick and Nicole's close relationship seems accurate.

"I never met a woman who was so loving and such a great friend," Resnick told ET in 1997.
But months after Nicole's murder, Resnick parlayed her friendship into a six-figure payday with the advance she received for her 1994 tell-all, Nicole Brown Simpson: The Private Diary of a Life Interrupted.
In the book, Resnick writes that she and Nicole's relationship took a romantic turn one night.
"Nicole was my best friend in every way, and it physically manifested itself in one evening. That was it -- nothing more," Resnick told ET in 1995.

In the miniseries, O.J. is also accused of spying on Nicole while she was getting intimate with other men. Resnick had similar claims when she spoke to ET.
"We used to check the bushes all the time to see if O.J. was out there," she said.
According to Resnick's interviews with ET, the miniseries could have possibly taken liberties with the truth with regard to Nicole's alleged drug use.
"Nicole wasn't into drugs," Resnick said.
In the miniseries, Nicole and O.J. are described as "the most undivorced divorced couple," but Resnick said that things had changed towards the end.

"Nicole was not interested in him any longer," Resnick said. "Nicole was very afraid of him."
