Getting into character for her role as real-life prosecutor Marcia Clark in "The People v. O.J. Simpson: American Crime Story" was quite the adventure for Sarah Paulson.

The four-time Emmy nominee prepared for the part by reading Jeffrey Toobin's "The Run of His Life: The People v. O.J. Simpson," on which the hit FX series is based, and by getting drunk off tequila with the real woman at the center of The Crime of the Century.

"I did meet her -- I drank a lot of tequila with her," the actress told Ellen DeGeneres of her first meeting with Marcia.

But how much is "a lot," exactly?

"It was really fun," said the "American Horror Story" star during an episode of "The Ellen DeGeneres Show" airing on March 8.

"It was like the mole kept moving all over her face in my mind. It was like, 'Is that you? Oh, now it's on your forehead,'" she continued. "It was a lot of tequila, yeah."

It sounds like Sarah needed a little liquid courage to steel her nerves while coming face-to-face with Marcia, who served as the lead prosecutor during O. J. Simpson's murder trial.

"I made a lot of weird sort of squealy pig noises because I was so excited," Sarah told Ellen of meeting Marcia. "I had spent so much time with my nose sort of in a book about her, her actual book [and] the Toobin book, that when I saw her, it was like seeing someone I'd idolized or had a terrible crush on for my whole life or something. She walked into the restaurant, and I just started going, 'Ahhh!' And she sort of looked around like this a very sort of terrifying experience for her."

But as terrifying as meeting the actress who was set to portray her may have been for Marcia, it was nothing compared to the fear she experienced watching the show for the first time, says Sarah.

"She is watching [the show]," said the "Carol" actress. "I think it was a very difficult prospect. The actual doing of it was less horrible than she thought it was going to be."

"[The O.J. Simpson case was] a very painful thing [for her]," added Sarah. "It's probably the most painful thing that she ever lived through -- certainly."

As for the new attention on the prosecutor, Sarah doesn't think it's a bad thing at all.

"[Marcia] is getting a lot of attention now, and I think the greatest part about it is that it's attention that was probably due her at the time but people were really believing what was being said to them -- that she was a kind of a shrew, ambitious b----," says Sarah.

"All of the words that you use to describe Marcia, if you described a man that way, would be positives," she continued. "And if you describe a woman that way, it's a pejorative."

Cheers to that sentiment, Sarah!
