Showtime, which just released its first Masters of Sex trailer, has also given fans a look at its new series Ray Donovan, starring a couple of silver screen powerhouses in Liev Schreiber and Jon Voight.

The title character, played by Schreiber, does the dirty work for LA's top power players. He's go-to guy who makes the problems of the city's celebrities, superstar athletes, and business moguls disappear.

The collateral damage from his work can be drastic, but it's of no concern to Donovan ... until his father (Voight) is unexpectedly released from prison, setting off a chain of events that unsettles his world.

Check out Showtime's first trailer for the intense-looking 2013 series right here ...

The series also stars Elliott Gould as Ray's long-time client and mentor, Paula Malcomson (The Hunger Games) as Ray's wife, Abby, along with Eddie Marsan (Sherlock Holmes) and Dash Mihok (I Am Legend).

Another sneak peek will air next week before the finales of Dexter and Homeland.
