Looks like Sarah Paulson owes Marcia Clark another apology.

The 41-year-old actress used her Emmys speech to graciously apologize to Clark for "carelessly and superficially" judging her -- and then left the prosecutor, who was also her date for the night, back in the theater.

"This is an enormous honor," Paulson told ET's Nancy O'Dell backstage, before remembering that she had left Clark back in the Microsoft Theater post-Emmy win.

"I left her… We won for Best Limited Series, I got up there and I didn't know I wasn't going to be going back to my seat," Paulson confessed. "Marcia is sitting [in the theater]. I couldn't really bring her up on stage with me."

While The People v. O.J. Simpson star may have inadvertently left Clark behind, she did take the opportunity to further gush about her "good friend."

"I pictured the two-dimensional person, because it's what we -- it's what we believed, and what we all saw, and what was fed to us through the trial, through the media at the time," Paulson said, elaborating on her Emmys speech. "Once I did any further looking, it became very, very clear what a deep, complicated, smart woman she was, and what battles she was fighting, so yeah, it became a very different picture."

According to Paulson, the challenges Clark faced as a powerful woman in the public eye are still very much present.

"You look at Hillary Clinton right now and go, 'Has anything changed?'" she said. "We've made some progress, but we've got a ways to go."

But back to Clark -- Paulson clearly felt guilty about leaving her friend in the dust.

"I left Marcia in the theater like a moron," she announced in the press room.

"Listen, it was a roll of the dice when I asked her to come with me, because they could've very easily not called my name, and then she'd be there, and we would've gone to get a chicken breast somewhere and have a cocktail and then go home," she added.

"But if it turned out this way, I would have been able to stand up in front of everyone with many, many eyeballs and say that, in the world, it was a collective failing for Marcia during the time of the trial," she shared. "Given what I know now, and given what we all know after the series, I think an apology was in order, so I was very, very happy to be able to do it in such a broad way."
