According to The Daily Star, the series will eventually delve into the beginnings of Prince William and Kate’s relationship as the time period for the show will lead up to the early Noughties, during which the Duke and Duchess first met at university. However, it is only expected to be a very small role, as the series will focus on the Queen’s reign during the late 90s to early 2000s, with a source saying that they will only cast the role if they find the right person for the job.

There is currently a call for actors between the ages of 16 to 21 to play Princes Harry and William for the final season, and casting agents are looking for "a strong physical resemblance" of the pair.
Will Kate appear in The Crown?
The fifth season will be landing on Netflix in late 2022, and sees Dominic West, Elizabeth Debicki and Imelda Staunton take on the roles of Prince Charles, Diana, Princess of Wales, and the Queen.
Chatting on Women’s Hour about playing Her Majesty, Imelda said: "I think my sort of extra challenge, as if I needed it, is that I’m now doing the Queen that we’re a little more familiar with. With Claire Foy, it was almost history and now I’m playing one that people could say ‘she doesn’t do that,’ ‘she’s not like that,’ and that’s my personal bête noire."
Casting directors are also looking for actors to play Harry and William aged 16-21
She added that it was "up to producers and directors" to decide to post a disclaimer about the show being a work of fiction, saying: "This isn’t verbatim; this isn’t taken from diaries. You’ve got to use your imagination, and I’d like to allow the audience a bit of intelligence. You can’t know that’s what Margaret and Elizabeth were talking about."
