The Ryan Murphy-produced FX series depicts some intense romance vibes between attorney Marcia Clark -- whom Sarah plays -- and Christopher, which the 41-year-old actress made sure to point out is drawn from TV drama, not actual confirmed reality.

"Marcia and Chris never made any confirmation about any of that, so we certainly weren't going to put any of that out as fact," she explained. "But, you know, it felt to me that there was something going on."

Sarah elaborated by discussing the procedural as a "reimagining" of who Marcia was.

"For me, it's kind of an exciting thing," she said of playing the role. "[Marcia] is who she is, I'm just trying to honor that, but she was not given any credit or respect at the time for the work she was trying to do."
