Premiering on Starz from today (Friday 5th April), the new series is led by Academy Award winner Julianne Moore and breakout star Nicholas Galitzine, who is set to star in the upcoming talked-about film release of The Idea of You.

Here, Moore and Galitzine star as the formidable Mary and George Villiers, a mother and son duo who would stop at nothing to further their family's name and nobility. While it may sound like a work of fiction, the series delves into very real true story of the Villiers and how Mary thrust George in to the pursuit of King James I, played by Tony Curran.

Their quest was a fruitful one to say the least, as they became the most powerful family in England during the Jacobean era.

But while their path to power may appear seamless, the seven-parter shows how the mother and son's own relationship was pushed to the limits and as per the synopsis: "George must prove to himself that he can be defined by more than just his beauty."
