Marcia Clark, the former Los Angeles County prosecutor who was the lead attorney on the O.J. Simpson murder case, says she blames herself for the controversial outcome of the case. 

Sitting down for a Dateline NBC interview set to air Sunday, Clark shed some more light on the inner workings of the case which captivated the world more than two decades ago. 

A preview of the pre-taped interview was released Tuesday; Clark sitting down with Josh Mankiewicz talks about not wanting Simpson to try on the gloves during the trial and how she felt when the jury foreman read "Not guilty." 

"It was physically painful," Clark says of the verdict. "And I thought of Ron [Goldman] and Nicole [Brown], and I thought, 'This is wrong.'" 

The double homicide has once again become a main topic of conversation following the recently launched FX series The People v. O.J. Simpson: American Crime Story.

So far, four episodes of the nine part series have aired. 

The two-hour Dateline special will also feature interviews with Kris Jenner, Denise Brown, Fred Goldman, Alan Dershowitz and Kato Kaelin, among numerous others connected to the case.

In the preview for the special, Clark — played by Sarah Paulson in the FX series — says she blames herself for Simpson going free.

"But at the end of the day, we really ... there was no way to reach that jury," she tells Mankiewicz. "There was no way to make them believe. There really wasn't."

Clark also says she was against Simpson trying on the gloves, which police said the killer left behind, during the trial. That iconic moment, when the glove appeared to not fit, was a massive blow to the prosecution. 

"That was not my call. That was not my call," she tells Mankiewicz. "I did not want him to try on the evidence gloves. I never did."

That idea came from co-counsel Christopher Darden, played by Sterling K. Brown in the FX series. Darden apologized to Clark for the massive blunder, she says. 

"And I said, 'It’s okay," says Clark. "If that lost the case for us, we were never going to win anyway'.”
