When it comes to transforming for a role, few actresses do it better than Sarah Paulson. During her five seasons on FX's "American Horror Story" Paulson has proved herself quite the chameleon. Whether she's portraying a ghostly hooker or sideshow Siamese twins, there's little the multi-faceted actress can't tackle head on. For her latest role, as prosecutor Marcia Clark in "American Crime Story: The People v O.J. Simpson," Paulson has once again pulled off an incredible transformation.

The 10-part series follows the 1994-95 trial of football star turned actor and commentator O.J. Simpson, who was arrested and tried for the brutal murder of his ex-wife Nicole Brown Simpson and family friend Ronald Goldman at her Brentwood, Calif., residence.

The trial would become a televised event making unwitting stars of its participants, including Clark who herself was tried in the court of public opinion for her demeanor, appearance and courtroom style. In fact, the hard-edged lawyer who was tasked with the job of prosecuting Simpson was regarded as unlikeable – even to Paulson. A 19-year-old college student at the time, she found herself guilty of judging Clark harshly, and while recreating the events of the case for television didn't change her opinion of its outcome, it did give her pause where Clark is concerned.

"It didn't change my opinion, but it made me more aware of my own judgmental nature," Paulson tells Headlines and Global News in an exclusive interview. "I was very young, I was 19, but I remember being quite convinced that Marsha was what I was being presented Marsha was."

"Now myself being in the public eye or being criticized or judged and all of that, it's a very unique position to be able to sort of look at it and go, 'God, I wish I had been on her side, just by virtue of the fact that she was a woman,'" she ads.

According to Paulson, it was the reaction of co-star Sterling K. Brown (who plays her co-counsel Christopher Darden) to Simpson's innocent verdict, after months of trial and the media circus that surrounded it, that really brought things home.

"He said when the verdict first came in his initial reaction was one of 'oh good,'" reveals Paulson. "It's the first time he saw one of his own community members being exonerated when normally his experience with the police was they were not there to serve and protect him. So I feel that same feeling as a woman, why wasn't I rallying around her for her? I wish I had done that."

When it came to Clark's unlikeable public persona, Paulson admits finding the human side of a working mother, going through a nasty divorce at the time, was never an issue. 

"I never thought about humanizing her because she is in fact a human being," she says. "I can't possibly think about how to make her likable or anything because to me she was instantly likable. She was dedicated and totally unshakable in her belief that he was guilty. There was nothing that was going to stop her from trying to prove it."

Paulson firmly believes Clark's Achilles heel was that she wasn't a showman and may not have realized she was trying a case in the court of public opinion as well as a courtroom – and on television sets all over the globe. "With cameras permitted in the courtroom, what was happening outside and the opinions being formed outside were almost more important than the ones happening inside the courtroom," the actress says.

"She wasn't a razzle-dazzle person, she believed if she gave the jury the evidence there would be no way they could vote any other way," says Paulson. "Given the climate post-Rodney King and given O.J's fame, given the shoddy work by some of the LAPD, it was a challenging perfect storm. I don't think it was Marcia losing that case; I don't think it was winnable at that time."

Critics are already applauding Paulson's stellar performance in the series, which can only be described as "addictive." For Paulson, already a member of the Ryan Murphy repertory company know as "American Horror Story," should Murphy call with a part in another true crime tale, she's up for the challenge.

"Here's the deal, I'm not stupid, right," she says with a laugh. "Ryan Murphy has given me my career, so if he keeps looking at me and going, 'Do you want to come and do this?' I'm going to say, 'You want me? OK!' I don't know why I would not want to do it. If he asked me to do another 'American Crime Story' I would be so grateful."

In fact, Paulson already has a story in mind that she's exclusively revealing to Headlines and Global News in the hope Murphy is listening, although he does have ideas for the next story in the series.

"I think he's talking about Katrina, so I think that's what it's going to be," she says. "But I sort of want to play Tonya Harding, I don't think I've mentioned it to Ryan, but I would love to play Tonya Harding. Everyone asks, 'Wouldn't you want to be Nancy Kerrigan?' No, I want to be Tonya Harding."

"American Crime Story: The People v O.J. Simpson" has a star-studded cast that also features John Travolta, David Schwimmer, Courtney B. Vance and Cuba Gooding Jr. as Simpson. It airs Tuesday at 10 p.m. EST on FX.
