Starz has set April 5th as the premiere date for its upcoming  psychodrama “Mary & George” starring Academy Award-winner Julianne Moore (Still Alice) and Nicholas Galitzine (Red, White & Royal Blue).  “Mary & George” is set to debut on Friday, April 5 at midnight on the STARZ app. On linear, it will debut on STARZ at 9:00 PM ET/PT in the U.S. and 10:00 PM ET/PT in Canada.

The seven-part limited series is inspired by the scandalous true story of a treacherous mother and son who schemed, seduced and killed to conquer the Court of England and the bed of King James I.

As previously announced, Julianne Moore plays Mary Villiers, Countess of Buckingham, who in 17th century England molded her beautiful son, George, to seduce King James I and become his all-powerful lover. Through outrageous scheming, the pair rose from humble beginnings to become one of the richest, most titled and influential players the English court had ever seen, and the King’s most trusted advisors. Nicholas Galitzine plays her son, George Villiers, a naïve romantic who alongside his ruthless mother was prepared to stop at nothing to get to the top and prove to himself that he can be defined by more than just his beauty and make his mark on history. Tony Curran (“Mayflies”) stars as King James I, whose desire to be loved and subservient to ambitious and beautiful young men, makes him dangerously at risk of being exploited by tyrannical lovers to the likes of Mary & George.
