The eccentric and naive personality of Ludwig II and the conflicts caused by his royal duties is reflected in the first part of the movie. The second part that is about the seclusive life he led seems to be based on the reports prepared to prove he is insane in order to abdicate him. As the diaries of Ludwig II were damaged during World War II, we don't know much about the real experiences he had in his seclusion. But his naive and sensitive personality does not match some of the behaviours depicted.
