Madonna is reportedly trying to land David Tennant and Cate Blanchett in a new musical titled ‘Wallis.’

Madonna thinks the pair would make a great King Edward VIII and Wallis Simpson, the American divorcée for whom he abdicated the throne in 1936. She is hoping to produce and direct the musical focusing on their lives.

A source told The Sun: “The final script is now written and the locations have been scouted. Madonna is now trying to assemble the cast and put the finances in place.

“The first scene of the film is an old woman in her nineties living on her own in a Parisian flat. She starts to tell her life story to her housekeeper. It turns out the old woman is Wallis Simpson.”

They added: “There will be a song for each decade of her life.”
