"Game Of Thrones" fans may even recognize some of the cast from Netflix's royal drama.
Some actors like Charles Dance took on similar roles in both series, while others like Gemma Whelan underwent complete character makeovers.
Here are 6 actors who have been cast in both series.
George R.R. Martin has always been clear about how the lives of real medieval kings and queens were a big inspiration for "Game of Thrones."
Therefore, it's only fitting that the fantasy drama shares a few things in common with Netflix's royal drama "The Crown" — including some of its cast members.
Here are 6 actors who have been cast in both series:
Charles Dance stays on brand in both series through patriarchy, daddy issues, and nobility. In "Game of Thrones," he played Tywin Lannister, the mean-spirited head of House Lannister whose first two children were incestuous, and whose third murdered him.
As Lord Mountbatten on "The Crown," Dance plays the semi-cool uncle to Prince Charles — that is until he conspires with the Queen to ruin the young prince's fledgling teen romance, and then seemingly establishes a coup to overthrow the British government.
In "Game of Thrones," Tobias Menzies is the cowardly Edmure Tully, Lord of the Riverlands, and brother to the great Catelyn Stark. Tully miraculously made it to the controversial final episode after disappearing for two seasons, but spoiler alert — he doesn't become King.
He doesn't become a King in "The Crown," either. As Prince Phillip, he instead assumes the lowly titles of Prince Consort, Duke of Edinburgh, Earl of Merioneth, and Baron Greenwich.
Stephen Dillane had a hard time as Stannis Baratheon, the younger brother of King Robert Baratheon, in "Game of Thrones." After his brother died, Stannis declared himself the rightful heir to the throne, and launched a campaign that included witchcraft and wizardry, child sacrifices, and several battles to claim it.
Dillane had it no easier as the English Painter Graham Sutherland on "The Crown," who was tasked with creating a portrait of the British Prime Minister, Winston Churchill.
Rupert Vansittart plays Yohn Royce in "Game of Thrones," a fiercely loyal ally of the Starks.
However, Vansittart's allegiances are a little less fixed in "The Crown," where he plays the newspaper editor Cecil King, who had a leading role in Lord Mountbatten's naughty coup to overthrow the British government.
In "Thrones," Gemma Whelan is Lady Yara Greyjoy, the fierce and uncompromising ruler of the Iron Islands. That is, until her uncle, Euron, returns and threatens her place on the Iron throne.
On season two of "The Crown," Whelan makes a hilarious albeit brief appearance as Patricia Campbell, the assistant to journalist John Grigg who criticized the Queen for making a tone-deaf speech, calling her a "priggish schoolgirl."
Fans will certainly remember Jonathan Pryce's terrifyingly pious performance as The High Sparrow in "Game of Thrones."
Pryce has recently been confirmed as the latest recruit for "The Crown," where he will take on the role of an older Prince Phillip in the final two seasons.
