Madonna is a "natural" filmmaker.
Abbie Cornish - who stars in the singer's new directorial effort 'W.E.', about the story of Britain's King Edward VIII and his American wife Wallis Simpson - confesses she was great to work with because she really "loves" learning and was "very well read".
She revealed: "Madonna is natural director. It's in her nature. She's a Leo and she really represents the Leos very well.
"She's a very smart woman, very well read. She really absorbs a lot about whatever she's involved in. I think she really loves learning. It was interesting to see her evolve throughout the filmmaking process. She's such a cool woman."
Abbie, who plays Wally Winthrop in the two-tier story taking place over separate timelines, also reveals Madonna's 14-year-old daughter Lourdes portrays a younger version of her character in the movie.
She added to MTV.com: "She actually plays a younger version of my character. She's a super-cute, younger version of my character."
Music producer William Orbit - who has provided two songs for the score of the movie - recently claimed the movie was Oscar-worthy and could see Madonna land a nomination for Best Director at the Academy Awards next year.
He said: "It's definitely Oscar-worthy and I'm not just saying that. I wouldn't comment on her past acting abilities so you know by me saying what I have that it's really a great film. I definitely think Madonna could be up for an Oscar for Best Director."
