Elizabeth Debicki, who will be seen next in Christopher Nolan's "Tenet," has been cast as the late, famous royal in the fifth and sixth seasons of "The Crown."
"Princess Diana's spirit, her words and her actions live in the hearts of so many. It is my true privilege and honour to be joining this masterful series, which has had me absolutely hooked from episode one," Debicki tweeted.
The hit Netflix series has followed the royal family through several time periods, starting in the late 1940s and early 1950s with Queen Elizabeth and Prince Philip's marriage and early careers.
Alongside Debicki, Imelda Staunton will play Queen Elizabeth in the two seasons. Claire Foy first played the royal in the original two seasons, and Olivia Colman took over in season 3.
Debicki will be one of the few non-English actors featured in the series, following John Lithgow's role as Winston Churchill. She will star alongside John David Washington and Robert Pattinson in Nolan's oft-delayed "Tenet" when it finally debuts internationally in late August and in the states in early September.
