The hourlong drama chronicles real-life sex researchers William Masters and Virginia Johnson‘s (Caplan) journey from their research in a Missouri hospital to their public debut on the cover of Time magazine.

At a Television Academy panel in April, executive producer Michelle Ashford talked to The Hollywood Reporter about the practical challenges of filming with the new castmembers: “Because we’ve hired the most fantastic cast in the world, they are all really busy so getting them in one place at the same time has been crazy.”

Season two of Masters of Sex premieres Sunday, July 13, at 10 p.m. on Showtime.
