In "Ray Donovan," created by Ann Biderman, Schreiber (Glengarry Glen Ross, Talk Radio, A View From the Bridge) plays the title character, a professional "fixer" for the rich and famous in Los Angeles. Although he solves the problems of others, he is unable to escape from his own. The cast also includes Jon Voight, Elliot Gould, Eddie Marson, Dash Mihok and Paula Malcomson. Allen Coulter directed the pilot; Mark Gordon and Bryan Zuriff are executive producers.

"Masters of Sex" is an adaptation of Thomas Maier's book "Masters of Sex: The Life And Times Of William Masters And Virginia Johnson, The Couple Who Taught America How To Love." The Showtime drama will chronicle the lives and romance of Masters (Sheen) and Johnson, who will be played by Lizzy Caplan ("Mean Girls," "127 Hours"). The pilot was written by Michelle Ashford and directed by John Madden; Sheen and his manager, Tammy Rosen, will serve as producers.
