Margaret Thatcher, Princess Diana and even President Trump have all been teased for future seasons of The Crown – but one figure who will definitely be appearing in the Netflix drama is Camilla, Duchess of Cornwall.

Speaking at the BFI & Radio Times Television Festival on Saturday (April 8), producer Suzanne Mackie revealed that The Crown creator Peter Morgan knows exactly when he wants to bring in the character of Prince Charles's now-wife.

"Peter's already talking about the most wonderful things," Mackie told fans at the BFI in London, appearing alongside the actress who plays Queen Elizabeth II – Claire Foy – and director Philip Martin.

"You start meeting Camilla Parker Bowles in season three. We have to be honest, season three and four are being mapped out."

Charles and Camilla married in a civil ceremony in 2005, but they knew one another for nearly 30 years and their relationship sparked a lot of controversy when Charles's ex-wife Diana infamously told Martin Bashir in a 1995 interview: "There were three of us in this marriage."

So, Peter Morgan has a lot to work from then...

As for season two – which yes, we're well aware hasn't even aired yet – director Martin and producer Mackie revealed that it will start with the Suez Crisis in 1956, and end with the resignation of Prime Minister Howard Macmillan in 1963.

"It has a different flavour. It feels like the '60s are with us and it has a slight shock of the new," Mackie explained.

Martin added: "The first season happened in a bubble; I think that Elizabeth and Phillip and Margaret are all in a world and everybody is in some ways supportive of them. And I think in the second season the world comes crashing in."

The Crown is expected to return to Netflix for season two in November.
