Charles and Diana on Season 5

Dominic West plays Prince Charles, while Elizabeth Debicki will take on the role of Diana. <P> <P>“I think people understand, because the cast has changed every two seasons, that this is not an imitation,” West says of playing Prince Charles to Tudum. <P> <P>“This is an evoking of a character. That’s really where the show lives: in the imagined conversations of their private life, which is something that no one knows. I think that’s what it gets a lot of criticism for. How can you know what they talk about in their private lives? The obvious answer is we don’t, but we have an incredible writer, a dramatist, who imagines based on exhaustive research, and that’s really part of the fascination of the show.” <P><P>
