Wagner is a 1983 film on the life of Richard Wagner. The title role was played by Richard Burton, who said it was the role he was born to play. It was directed by Tony Palmer and written by Charles Wood.
Other main roles were played by Vanessa Redgrave, Gemma Craven, Marthe Keller, Ronald Pickup, Miguel Herz-Kestranek and László Gálffi.
Sir John Gielgud, Sir Ralph Richardson and Sir Laurence Olivier played ministers of Ludwig II of Bavaria. This was the only film in which these three actors ever appeared on screen in the same scenes. It was also the only film in which Richard Burton and Laurence Olivier both appeared.
I will post part 4 of the film when it becomes available on YouTube.
