Network: Showtime
Stars: Michael Sheen, Lizzy Caplan, Caitlin Fitzgerald, Nicholas D'Agosto, Teddy Sears
Premieres: September 29

Why we're excited: Not much is known about this series other than it's based on Thomas Maier's book Masters of Sex: The Life and Times of William Masters and Virginia Johnson, and that Sheen and Caplan will portray the pair, real-life leaders of the sexual revolution/pioneers of the science of human sexuality. A TV show with that premise, on an uninhibited network like Showtime, starring the always sexy Caplan? Yeah, we'll be there.
