Creator Breakdown: Marilyn Manson (the person) had a bout of serious depression whilst writing "Eat Me, Drink Me."
Executive Meddling: Manson originally wanted to use a nude photo of himself as a baby for the cover of Portrait of an American Family. The label was Squicked out and shot down the idea, not being very eager about accusations of child pornography.
Mean Character, Nice Actor: Off the stage, Marilyn Manson is a sweet, sensitive, polite and kind-hearted Nice Guy who deeply cares about his fans. When interviewed by Michael Moore about how his music is allegedly responsible for the titular massacre of Bowling for Columbine, he answers with genuine sadness that people ought to reach out and understand social outcasts like the two boys rather than label them as monsters.
