I was amazed to read that the surviving members of the band wanted that movie to be primarily about what Queen did after Mercury’s death.

They were a parody of other comics as well, notably X-Men (hence the “teenage mutant” part) and Howard the Duck.

Steven Tyler didn’t think it was funny

This Is Spinal Tap should have had one of the band members with a pre-pubescent girlfriend, but I guess that would have been too over the top even for them.

In case anybody doesn’t know this, '70s rockers were notorious for their consumption of literally underaged girls. Tyler in particular even assumed legal guardianship of his bit of jailbait so he could take her on tour with him.
