As a reminder, the cast of season three is filled with all new actors. Since the show follows the rise and fall of Queen Elizabeth II's reign in the British monarchy, we always knew that a few different stars were going to play the key characters over the years so as to accurately portray their progressing age (instead of, say, using extensive prosthetic makeup), and the season three teaser features The Favourite's Olivia Colman stepping into the heels previously worn by Claire Foy. She's the only character we get a glimpse of, but we can assume the new Princess Margaret (aka Helena Bonham Carter) will look just as incredible.
Netflix shared the teaser via the UK drama's Twitter page, writing "Season Three of The Crown, starring Olivia Colman as Queen Elizabeth II, arrives 17th November."
