In between the second and third season of The Crown, there was a similar event. Claire Foy (Wolf Hall) stopped portraying Queen Elizabeth, Olivia Colman took over. In the fifth season, Imelda Staunton (A Confession) will take over from Colman. It's not just the Queen who's replaced, a lot of the cast will be recast including Princess Margaret.

The fourth season of The Crown is expected to release later this year. The fifth season was originally supposed to be the last, earlier this month it was revealed that there is going to be a sixth.
