New details about casting for The Crown‘s final two seasons have come out. The latest: Princess Diana is going to be portrayed by 29-year-old Australian actor Elizabeth Debicki in seasons five and six of the hit show. Debicki is known for her roles in WidowsGuardians of the Galaxy Vol. 2, The Great Gatsby and this year’s release, Tenet.

“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,” said Debicki in a statement provided by Netflix.

Princess Diana will be played by Emma Corrin in the Netflix series’ upcoming fourth season.

Debicki will join a new cast including Imelda Staunton as Queen Elizabeth, Lesley Manville as Princess Margaret and Jonathan Pryce as Prince Philip. Staunton follows in the footsteps of Olivia Colman and Claire Foy in the role.

The Crown was initially supposed to end after the fifth season, but creator Peter Morgan changed his mind and decided to extend it one more season.

“As we started to discuss the storylines for Series 5, it soon became clear that in order to do justice to the richness and complexity of the story we should go back to the original plan and do six seasons,” Morgan stated in July. “To be clear, Series 6 will not bring us any closer to present-day — it will simply enable us to cover the same period in greater detail.”

The sixth and final season will take place in the early 2000s, so we won’t be seeing Kate Middleton or Meghan Markle storylines in the show.

The Crown’s fourth season is slated to premiere later this year.
