Abbie Cornish - who stars 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."
