Both series will return on Sunday, July 13 and air 12 hour-long episodes for Season 2. "Ray Donovan" aired its first season in the summer behind the final season of "Dexter," while "Masters of Sex" wrapped its freshman run last December.
The pairing likely means that new drama "The Affair" will be scheduled alongside Showtime's highest-rated series "Homeland" in the fall. Showtime has yet to announce a premiere date for either series. "The Affair" centers on an extramarital relationship and its effects on the people involved.
"Ray Donovan" is the premium cable network's first freshman series to average over 5 million viewers a week, drawing 5.7 million viewers during its first season across all platforms. "Masters of Sex" averaged 4.8 million viewers airing after "Homeland."
"Donovan" stars Liev Schreiber as LA’s best professional fixer, the man called in to make the city’s celebrities, superstar athletes, and business moguls’ most complicated and combustible situations go away. Season 2 will deal with the aftermath of the killing of a Boston mobster.
"Masters" stars Michael Sheen and Lizzy Caplan as the real-life, pioneering sex researchers William Masters and Virginia Johnson from the 1950s.
"Masters of Sex" recently added Keke Palmer ("Akeelah and the Bee") and "Breaking Bad" alum Betsey Brandt in recurring roles for the upcoming second season. Palmer will portray Coral, the nanny hired by the Masters to care for their new baby, while Brandt will play Dr. Masters' new secretary. Annaleigh Ashford, who recurred as lesbian prostitute Betty Dimello during the first season, has been promoted to a series regular for Season 2.
Cast additions for "Ray Donovan" include Heather McComb ("The Event"), who will play Patricia, a working-class mother who befriends Bunchy Donovan (Dash Mihok), and Andrea Bogart ("General Hospital") recurring as Megan Volcheck, wife of FBI agent Volcheck (Kip Pardue). Hank Azaria, Sherilyn Fenn, Ann-Margret and Wendell Pierce ("The Wire") have also booked multi-episode arcs.
Showtime’s next original scripted series premiere is the horror thriller "Penny Dreadful" on Sunday, May 11 at 10/9 p.m. CT. Meanwhile, veteran series "Nurse Jackie" and "Californication" will return on Sunday, April 13.
The sophomore seasons of "Ray Donovan" and "Masters of Sex" will air back-to-back at 9/8 p.m. CT and 10/9 p.m. CT, respectively, starting on Sunday, July 13 on Showtime.
