MADONNA wants the classy actress Cate Blanchett to star in her new musical.
The singer is set to direct and produce Wallis - following the life of American socialite Wallis Simpson, who Britain's King Edward VIII gave up his throne to marry - and wants the Notes On a Scandal actress to take on the lead role opposite Doctor Who actor David Tennant.
A source told Britain's The Sun newspaper: "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 is an old woman in her 90s 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."
Madonna had been planning to start work on the film last year - but it was put on hold while she finalised her divorce from film director Guy Ritchie. - Bang
