Could this be?

Speculation is growing that none other than Helena Bonham Carter is set to join the cast of The Crown when it returns for a third series. The actress is rumoured to be taking on from the role of Princess Margaret as the show jumps forward a few decades. Olivia Coleman is already confirmed to play Queen Elizabeth, so now we wait in anticipation for the announcement of Princess Margaret. According to the Evening Standard, Bonham Carter has a personal connection to the Princess Margaret part - her home in Oxfordshire, Mill House, was previously owned by Margaret’s former lady-in-waiting, Jane Stevens and Bonham is well familiar with playing the role of royalty having done so in The King's Speech. One thing is for sure, people on Twitter are hoping the news is true.

Helena Bonham Carter is just making her way through the royal family. The Queen Mother, now Princess Margaret, I hope I live long enough to see her appear as Princess Charlotte in something.

@Pricewrite Pleased with this! Though strange to think she played Princess Margaret's mother in The King's Speech..!
