Welles has some interesting ideas on Macbeth. Not all come off. The Scottish accents employed by the cast make the whole thing sound like a particular violent episode of Dr Finlay's Casebook. Good black and white photography - mainly black. Welles' costume at the end of the film makes him look like the Statue of Liberty. I don't think this is the version for you if you don't already know the play.
Having watched Joel Coen's amazing version of the same play, I was interested in seeing what other directors did with the material, and there's no greater director than Orson Welles so I was pretty excited to see this. The shoestring budget is pretty conspicuous at times but this is a dark disturbing interpretation. Whereas Coen focussed heavily on the bird imagery throughout the text, Welles - without explicitly stating it - seems to be more interested in the childlessness of the Macbeths(something which is key to understanding their characters. The very first images of the witches makes that clear with the weird sisters seemingly conjuring up a foetus. Possibly the darkest mage in all of Welles' cinema. There's a couple of terrific one-takes in which Welles moves the camera in a way only he could. Yes some of the costumes aren't up to Hollywood standard, neither are some of the accents but those are pretty superficial complaints for a film so eerie and haunting.
