The great Michael Jackson once offered to make a Harry Potter musical for J.K. Rowling. The story came out during a recent Oprah Winfrey interview special with the bestselling author.

“Were you reluctant to increase the empire?” asked Winfrey in the video embedded above. Rowling replied: “It could be so much worse. Michael Jackson wanted to do a musical … I said no to a lot of things. For me, I love the films, I love the books, and there’s elements that I love around it.”

Winfrey called it “one of the most fascinating interviews I’ve ever conducted.” The women spoke at Edinburgh’s Balmora Hotel, the place where Rowling finished Harry Potter & the Deathly Hallows. Rowling mentioned that if she wanted, she could write more Harry Potter books. She explained: “I definitely could write an eighth, ninth, tenth book. I could, easily.”

Rowling recently made the news for being the first winner of the 500,000 kroner (approximately $75,000) Hans Christian Andersen Literature Award.
