Foy played a young Queen Elizabeth in the first two seasons of the Netflix original drama series based on the royal family. The seasons took place between the years 1947 and 1964.

Every two seasons, the actors are changed to follow the characters aging throughout the family history. To end Season 4, Olivia Coleman passed on the role to Imelda Staunton to take over the role of Elizabeth, showing the events that happened throughout the 1990s and onward.

In an interview with Netflix, Staunton found playing the role of the queen in the 1990s “familiar yet frightening.”

She said, “I think the challenge that I felt for myself—the extra challenge, if there wasn’t enough on my plate—was to be the queen that people recognize much more now, the older queen.”

“Claire Foy’s [version] was almost a costume drama because it seemed so long ago, and then Olivia Colman’s was, again, like a period piece. [This season] just feels so much more present. I thought, ‘I can’t fool anyone now,’” she continued.

“The Crown season 5 is out, and the first thing I am seeing is CLAIRE FOY back on our screen! Absolutely screaming because she is by far the best portrayal of The Queen I have ever seen. Already obsessed with this season,” a fan tweeted.

One fan exclaimed, “When i tell u all i screamed when i saw claire foy being back for some minutes!”

“my [favorite] genre is claire foy coming back for flashback elizabeth scenes,” tweeted another.

“She couldn’t help but appear and steal the show from everyone, she had to do it,” a Twitter wrote in a translated tweet, “Claire Foy THE queen.”

“Claire Foy always returning to [The Crown], as it should be, the only queen we need and deserve,” one user wrote in a translated tweet.

“claire foy guaranteeing in just a few seconds with her eyes her next emmy as queen Elizabeth,” another said in a translated tweet.

“Every single second is an exquisite, chills-inducing masterpiece. But, a [Claire Foy] cameo in the first 3 mins is just plain decadence. Usually Easter eggs are meant to be sprinkled in. But, [The Crown] Season 5 opens with one. Yay, finally—it’s back,” another fan exclaimed.

“Claire Foy in the first episode of season 5 is a pleasant surprise,” another user tweeted.

Another added, “so heartwarming to see claire foy as young Queen Elizabeth again in Season 5.”

“CLAIRE FOY HAS A CAMEO IN THE CROWN SEASON 5!!!!!!! I’M CRYINGGGG,” another fan wrote.
