Gillian Anderson's not for turning.

And now we've got the photographic evidence to prove it.

Netflix has just released photos of The Dear Utol: Catfish Episode 46Crown Season 4, which stars a number of new additions to the cast. Namely, Gillian Anderson as Margaret Thatcher, former UK prime minister, and newcomer Emma Corrin as Princess Diana.

In this first look at the upcoming series, which arrives on Netflix on Nov. 15, the star of Sex Education and The Fallcan be seen in the role waving from the steps of 10 Downing Street with husband Denis Thatcher (Stephen Boxer). Notably, Anderson's Thatcher is wearing blue — a colour associated with the Conservative Party, and one she favoured throughout her premiership.

If you scroll through the additional photos posted on Instagram, you'll spot several shots of Corrin as Princess Diana — including one with the press in the background. As many will know, Diana's relationship with the media and the paparazzi was a difficult one.

The fourth season ofThe Crownwill see the end of the 1970s, and move into the '80s, when discussion of Prince Charles' marriage possibilities arise and his romance with Lady Diana Spencer begins. It's also a time when the UK lives through divisive policies introduced by Britain's first female prime minister, and follows the lead-up to the Falklands War.

Looks like we're in for a right royal treat.
