Courthouse News Service has this Philadelphia suit against the Warhol Foundation:

A family claims Andy Warhol and director Paul Morrissey tortured their late father when he was 14 years old by filming him while smoking pot and including the footage in their movie, “All Aboard to Dreamland Choo Choo.” They said Morrissey and the Andy Warhol Foundation are still making money off DVDs of the movie. Richard Toelk’s daughter and two sons called the movie “child pornography” in their complaint in Philadelphia Federal Court.  […] The pair filmed Toelk “throughout his teen-age years,” his family says in Philadelphia Federal Court. The family sued Morrissey, the Andy Warhol Foundation for the Visual Arts, Image Entertainment and Score-Sarx Company for invasion of privacy, claiming “All Aboard” made them suffer “great embarrassment and shame.” They demand $300,000.
