"The Crown" is preparing to bring the much-awaited storyline about Princess Diana as played by actress Elizabeth Debicki. And she is "incredibly excited" to take over the role of Emma Corrin.

Last month, it was announced that Elizabeth Debicki will play the role of Princess Diana in "The Crown" Season 5 and 6. The "Tenet" actress has apparently been hooked to the series that tells the story of the British monarchy from the time of Queen Elizabeth II's coronation in the 1950s.

Appearing on the Thursday episode of "Good Morning America" alongside "Tenet" co-star Kenneth Branagh, the 30-year-old actress opened up about being "overwhelmed" when she received the role. She also talked about playing her part as Kat in the movie "Tenet," the biggest movie to release after coronavirus lockdown.

"When [creator] Peter Morgan asked me to do it, I was quite overwhelmed," Debicki said. "But I've had a little bit of time to process it now, and I think that I'm actually just incredibly excited to do it. And she's such an important figure. She was such a remarkable human being, and so the idea of stepping into it is daunting but very exciting."

Debicki is known for her numerous roles in the movies like "The Great Gatsby," "Everest," "Guardian of the Galaxy Vol. 2" and television series like "The Night Manager" and "The Kettering Incident." However, to witness her portrayal of Princess Diana, fans will have to wait much longer.
