No one knows Marcia Clark better than perhaps Sarah Paulson.

That’s because the actress studied her extensively for her role in “The People v. O.J. Simpson: American Crime Story,” right down to the perfume she used to wear. Paulson described how she prepared for the role with Bobby Cannavale for Variety and PBS’ “Actors on Actors.”

The two-part fourth season premiere of “Variety Studio: Actors on Actors” airs June 12 and June 19 on PBS SoCal. Presented by Shopbop/East Dane, the episodes will also be available to stream on Variety.com.
