Reportedly, the film's director Ken Russell walked out of a revival screening of this movie saying: "What idiot made this?".
After the film had debuted the picture's director Ken Russell later said that his choice to make the movie was the biggest mistake of his career.
Ken Russell plays a director in the film. In his autobiography he explains that the actor who was to play the director was too drunk to work and so Russell played the part himself. Later the actor--who was too drunk to work--filed a complaint and the actors union insisted the scene be re-shot with a "real" actor and union member. This would have been very expensive as the scene involved a battle sequence--but it turned out that Russell who had started as an actor years before he was a director still had an acting union membership--so he was able to pay up his past dues and the scene remained in the film. Russell went to in the later part of his career to play parts in various films for himself and for others.
A major piece of advertising art (a shot of Rudolf Nureyev embracing Michelle Phillips) had to be retouched in mid-campaign after someone noticed he was wearing a trendy Seventies tank watch that didn't exist in the Twenties - a mistake clumsily corrected by airbrushing out the chunk of his wrist bearing anachronistic timepiece.
Romantic lead co-stars Rudolf Nureyev and Michelle Phillips got along so poorly during the making of this film that they were reported to have engaged in an on-set slapping match during shooting of the love scenes.
