Welles would maintain mixed emotions about "Macbeth". In a 1953 lecture at the Edinburgh Fringe Festival, he said: "My purpose in making "Macbeth" was not to make a great film – and this is unusual, because I think that every film director, even when he is making nonsense, should have as his purpose the making of a great film. I thought I was making what might be a good film, and what, if the 23-day day shoot schedule came off, might encourage other filmmakers to tackle difficult subjects at greater speed. Unfortunately, not one critic in any part of the world chose to compliment me on the speed. They thought it was a scandal that it should only take 23 days. Of course, they were right, but I could not write to every one of them and explain that no one would give me any money for a further day's shooting . . . However, I am not ashamed of the limitations of the picture."
