With just over two weeks to go until the new series of The Crown , Netflix has unveiled a new trailer showing more of what fans can expect from season four.

And while past clips from the upcoming series have focussed more on the existing cast and newcomer Emma Corrin , this latest teaser puts Gillian Anderson in the spotlight.

The former X Files star is joining the regal Netflix drama as former prime minister Margaret Thatcher , and the new trailer sees her going toe-to-toe with Olivia Colman as Queen Elizabeth II .
