Patch Adams

Comment: "Rumor has it", that the Real Patch Adams did not like his
portrayal done by Robin Williams in the movie.

Additionally, Patch Adams did not receive any money/payments either from
the movie, but it was alleged that he was supposed to have, in order to be
able to build a children's hospital.

Hardly authoritative, but the TVTropes article on the film does say that the real Patch Adams thought that the movie oversimplified his views and philosophies and was also upset that they changed one of his male friends into a woman for the film in order to add a love interest that wasn't present in real life and had Patch commit several felonies in the film.
