Princess Diana’s biographer Andrew Morton was “shocked” by the depiction of the “crown”.

Andrew Morton – who famously interviewed Princess Diana before her death – says that Elizabeth Debicki’s portrayal of the late Queen “took my breath away”.

“It left me breathless, and it took me back all those years,” Morton, who wrote the 1992 Tell-All Diana: Her True Story and serves as an advisor on the Netflix series’ fifth season, told Good Morning on Friday America. “I mean, I don’t say that very often, but I was shaken.”

The show’s fifth and critically acclaimed season explores the disillusionment of the marriage of Princess Diana (Debicki) and then-Prince Charles (Dominic West).

After the book’s publication, it was revealed that Morton and Diana had married Dr. Using James Colthurst as a middleman to submit written questions to Diana and then she recorded responses to send back.

“What I didn’t realize at the time was her sense of isolation, her despair within the royal system,” Morton recalls.

After Diana’s death in 1997, Morton published an updated version of the book, revealing that the princess herself was his main source of information.

Morton said Netflix made sure its portrayal of the now 69-year-old journalist was as accurate as possible.

“The writers asked me all kinds of questions, like what color wallpaper is in my daughter’s bedroom because that’s where I had an office for a while,” Morton says.

Morton did not respond to a request for comment from The Post.
