The clip features Queen Elizabeth going head to head against Margaret Thatcher, who is threatening to steal the spotlight.
The Prime Minister answers that she is "comfortable" with having enemies.
The head of the BBC has apologized to the brother of Princess Diana for a journalist's use of fake bank statements to lure her into the 1995 Panorama interview she gave after her split from Prince Charles. You can't really control if they do and also if you start thinking about, "I wonder what they'll think". I also get a chance to explore them both as mothers.
Reacting on Twitter, excited fans said the trailer had them shaken, while others praised Gillian Anderson's portrayal of Thatcher.
Britain's first female prime minister, Baroness Thatcher, creates conflict with the Commonwealth after leading the country into the Falklands War, only increasing friction with the palace. Corrin is due to make her debut as Princess Diana when the show opens this November.
The Prince of Wales's romance with a young Princess Diana also comes under the spotlight, played by Josh O'Connor and newcomer Emma Corrin. Writing Thatcher and the Queen as mothers was probably an angle that no one has explored before. During Olivia and Helen Bonham Carter's appearance in 2019's episode of "Graham Norton Show", the actress who portrays the role of Queen Elizabeth II in season 3 and 4 of the series revealed that William hasn't watched the show.
The season will explore the ups and downs of that relationship, including Diana's propulsion from teenager to public figure, their global news wedding and equally worldwide travels, and Diana's desperation to feel a true part of the family. We were filming the scene when you first see her in the wedding dress - I think it was Lancaster House in London - and I had a team of about 10 people helping me put it on because it's massive. Their marriage, and Prince Philip's involvement, will be chronicled in Netflix's upcoming season of The Crown.
"I feel I've got to know Diana like you would a friend", she told British Vogue.
The Crown season 4 arrives on Netflix on November 15th.
Stephen Boxer also features as Denis Thatcher alongside Rebecca Humphries as Carol Thatcher and Freddie Fox also features as Mark Thatcher.
