As the series moves into the ’80s, Corrin makes her appearance as Diana, when talks of Prince Charles’ marriage possibilities arise and marks the start of his romance with Lady Diana Spencer. One of the stills show Corrin (as Princess Diana) making a red carpet entrance in a stunning lilac gown alongside Prince Charles, played by Josh O’Connor.

A second photo shows her in a pale yellow day suit, and flashing a replica of Diana’s iconic blue sapphire engagement ring.

The royal couple’s wedding day, which took place on July 29, 1981, will likely be a subject of focus as well.

The new season will also feature Anderson as Margaret Thatcher, who is elected the British prime minister (Thatcher served from 1979 to 1990). She navigates a complicated and somewhat strained relationship with Queen Elizabeth II, played by Academy Award winner Olivia Colman.

The rest of the cast of The Crown season three remain, with Helena Bonham Carter reprising her role as Princess Margaret and Tobias Menzies as Prince Philip. Erin Doherty and Emerald Fennell will continue to play the roles of Princess Anne and Camilla Parker-Bowles.

Produced by Left Bank Pictures and created by Peter Morgan, the filming of the series wrapped up in March this year.
