We’ve met Bill’s mother and heard frequent reference to his father—but this summer on Masters of Sex, it’s time to meet Virginia’s parents.

EW has learned exclusively that Frances Fisher and Michael O’Keefe will play mother and father, respectively, to Lizzy Caplan’s Virginia Johnson when they appear on season 3 of Masters of Sex (premiering on Showtime July 12). Fisher and O’Keefe are each booked for two episodes.

Johnson’s parents will pay their daughter a surprise visit, where her mother will question both Virginia’s controversial work at the office and her lifestyle choices at home. (Yep, sounds about right.)

This year, Masters of Sex jumps ahead four years to 1965 and the debut of Masters and Johnson’s Human Sexual Response—a groundbreaking journal that put the pair on the national radar and the eventual road to stardom, but also made them the focus of intense scrutiny. EW premiered the show’s season 3 trailer here.

Both Fisher and O’Keefe are longtime TV vets. Fisher most recently starred on the ABC’s short-lived Resurrection, though she’s best known for playing Kate Winslet’s mother in 1997’s Titanic. O’Keefe is an Oscar nominee (The Great Santini) perhaps best remembered as Danny Noonan in Caddyshack; he recently recurred on season 4 of Showtime’s Homeland.
