Creator Breakdown: In 1991-1993, Madonna went into overdrive pushing the boundaries over sexual content in her work, culminating in the release of the book Sex, the album Erotica and sexually explicit videos for the title track and "Justify My Love", and the movie Body of Evidence, which had Madonna play a nymphomaniac who literally fucked her weak-hearted husband to death. This led to a critical backlash of epic proportions. Madonna has since said that those three years were largely the culmination of her anger at her critics over her sexually charged persona and that she went overboard largely as a "fuck you, I'll be even MORE sexually explicit and raunchy and make money doing it and have you all talking about me even while you bash me".
Dye Hard: She's a natural brunette, but she has dyed her hair a variety of colors, most commonly blonde.
Executive Meddling: NBC forced Madonna to re-edit the footage of her on the cross during the concert special for the Confessions Tour.
Name's the Same: Madonna has two totally different songs called "Forbidden Love".
Old Shame: While "Holiday" is a concert staple, Madonna has done her best to make sure the video for the song never sees the light of day.
In the late '70s she starred in a zero budget, trashy film called A Certain Sacrifice. It wasn't released at the time, but after she hit it big the director naturally tried to cash in, which she strongly objected to.
Reality Subtext: "Me Against Madonna", Mad TV music video parody of the Britney Spears song "Me Against the Music", which portrayed Madonna (post American Life) hunting down Britney Spears so that she can bite her neck and drain her "youth and energy".
