Showtime has announced that Tate Donovan will be guesting starring in the third season of Masters of Sex.
Donovan will guest star in two episodes as Graham, “a confident scientist whose relationship with Margaret Scully (Allison Janney) brings them to Masters and Johnson’s clinic.”
Season three of the series is set in 1966 when the famed duo Masters and Johnson are dealing with the glare of the national spotlight as their sex study is finally unveiled. Masters and Johnson’s work will have a profound impact on contemporary relationships, especially their own evolving three-way “marriage” with Masters’ wife Libby (Caitlin FitzGerald).
Masters of Sex returns on July 12 at 10 p.m. ET/PT
