The Material Girl stepped behind the camera to direct the historical drama about American divorcee Wallis Simpson and British monarch King Edward VIII, who gave up the throne for their romance.
Madonna has now revealed her teenage daughter Lourdes was due to play Simpson as a youngster, but the pop superstar decided not to include the scene.
She tells MTV, "There was a scene where she played Wally as a young girl. And I just kind of dragged her in at the last minute. It was quite unfair of me what I did and what I asked her to do.
"But she was really great and then I ended up cutting her out of the film. Ruthless, I know. I said, 'Sorry babe, you're on the cutting room floor.' She took it like a champ."
