Ludwig's cabinet and doctors have him declared insane and he is deposed, when in reality the extent of his mental health issues is still up for debate.
Not sure if it's an institution but Otto is kept in a room with bars on the window. Ludwig is also kept under house arrest and treated by psychiatrists.
Otto is declared insane and attempts to bite the men restraining him. In a rage Ludwig threatens violence against his cabinet and throws a glass at his servant.
No slurs but Ludwig was Catholic and struggled with his sexuality, and homosexuality was punishable at the time. Ludwig's cabinet are critical of his homosexual relationships.
Sort of. Ludwig and Elisabeth are first cousins and share a kiss, but they ultimately remain friends. He is engaged to marry her sister Sophie but calls it off.
Yes, but it's very mild. There is full frontal and rear nudity of a young man but he is shot from a distance and not in a sexual situation (he is swimming). Ludwig holds an "orgy" but the scene only shows several nude and scantily clad men, no sexual acts on screen.
