Fridge Brilliance: It always bugged me how annoying and unprofesional Amadeus was, and how inaccurate the film was. But, since Salieri is crazy, he probably has a bad memory.
A question from this troper (who is studying music in school): If you're referring to Mozart as Amadeus, it's widely accepted that he was in fact like that in real life. He was notorious for have awful manners, a toilet bowl sense of humor, etc. The film is incredibly accurate in that respect.
For instance, he wrote a little part-song called Lech Mir im Arsch. Wanna guess how that one goes?
