The third and fourth installments of The Crown are being filmed back-to-back, which means that although we may have to wait until 2019 for season 3, season 4 could follow soon after.

The cast and crew have been spotted filming in Liverpool, which many fans are speculating may be being used to replicate Washington.

The images released from season three show Olivia Coleman as the Queen, Helena Bonham-Carter as Princess Margaret, Tobias Menzies as Prince Philip and Ben Daniels as Margaret’s husband, Antony Armstrong-Jones, also known as Lord Snowdon.

When the news was first announced that Broadchurch’s Olivia Coleman was to replace Claire Foy as Queen Elizabeth, the actress joked: “I'm going to play her Welsh,” and admitted that she had big shoes to fill. “I’m so thrilled to be part of The Crown. I was utterly gripped watching it. A proper ‘just one more’ feeling… I think Claire Foy is an absolute genius. She’s an incredibly hard act to follow… I’m basically going to rewatch every episode and copy her!”

The official air date is yet to be announced.
