The Crown will be refreshing its cast throughout the run of the entire series.
That much has been clear ever since the groundbreaking Netflix drama premiered last year.
Given that the show will span various time periods throughout Queen Elizabeth II's reign, it would be difficult to keep the one actress in the role.
The wonderfully talented Claire Foy did the role a lot of justice, and her efforts were rewarded with a Golden Globe for The Crown Season 1.
The show amassed a huge following for its portrayal of Elizabeth's earlier years, and the freshman season took us all the way up to 1955.
Viewers still have one more season left with Foy. The Crown Season 2 debuts Friday, December 8 on the streaming giant and that will mark the end of Foy's tenure with the series.
Colman will assume the role for the following two seasons, and that will chronicle the further adventures of one of the most influential women in the world.
Colman has an impressive track record when it comes to the small screen. She co-starred alongside David Tennant on BBC America's Broadchurch which wrapped its three-season run earlier this year.
She also appeared on The Night Manager, and that role found the star nominated for both a Golden Globe and an Emmy Award. Will The Crown be the show that secures Olivia some awards?
Time will tell.
Little is known about the upcoming season of the Netflix juggernaut.
What we do know is that Michael C. Hall will appear as JFK, so the show will continue to give viewers glimpses of one of the most historical people around.
