After two steamy seasons, what lies ahead for sexual scientists William Masters (Michael Sheen) and Virginia Johnson (Lizzy Caplan) when Masters of Sex returns this summer with a new season?

Plenty, as evidenced by this behind-the-scenes video promoting the upcoming season, which will see the action spring forward from the repressive 1950s to the swinging ’60s, picking up in 1967, six years after the events of the season-two finale.

“This is them starting to become public figures,”; say Sheen of his and Caplan’s characters, mirroring the journey of the real-life Masters and Johnson.

“I don’t think there’s anything I need an audience to know,”; adds Sheen of the new season. “They just need to watch the show.”;

The third season of Masters of Sex premieres Sunday, July 12.
