A couple of new trailers have been released for two new pay cable drama series.  Showtime has unveiled an extended look at its new series Ray Donovan, which stars Liev Schreiber as a “fixer” for the rich and famous in Los Angeles whose life is complicated when his powerful father—whom he may or may not have framed—is unexpectedly released from prison.  Despite the bland title, the show actually looks like a fairly interesting character drama with a pair of strong performances by Schreiber and Jon Voight.  The series premieres on Showtime on Sunday, June 30th.

Additionally, Starz has unveiled a new look at its period series Da Vinci’s Demons.  From executive producer David S. Goyer (Batman Begins), the show stars Tom Riley as the titular artist/inventor/swordsman/idealist living in Renaissance Florence, struggling to exist within the confines of his own reality and time as he begins to not only see the future, but invent it.  The series premieres on Starz on Friday, April 12th.  Hit the jump to watch the trailers for Ray Donovan and Da Vinci’s Demons.

Here’s the synopsis for Ray Donovan:

Set in the sprawling mecca of the rich and famous, RAY DONOVAN does the dirty work for LA’s top power players. The one-hour drama series stars Liev Schreiber as the go-to guy who makes the problems of the city’s celebrities, superstar athletes, and business moguls disappear. This powerful family drama unfolds when his father, played by Jon Voight, is unexpectedly released from prison, setting off a chain of events that shakes the Donovan family to its core.
