This production was discussed at my U3A class yesterday, after someone mentioned they'd been put off by the violence.
It a play I like and am familiar with, having taught it as an O'Level set text many times. Every scene seems to move the plot forward, unlike say,
Hamlet, my least favourite of the tragedies. My favourite 'film' version is the Polanski one with a naked sleep-walking Lady Macbeth played by Francesca Annis, I think, (unlikely, in a Scottish castel) and Martin Shaw as Banquo.
It's powerfully supernatural and violent play. As is often said, Shakespeare's resources were few and he had to do it all with words. There's lots of evidence from other plays around at the time, as well as Shakespeare's though, that his audience really liked a visceral depiction of violence in their drama. I remember being shocked by stage directions for a play called
Tamburlaine that said 'Brains himself on the bars of the cage'
I think directors like Peter Hall and Trevor Nunn just went all out to find new interpretations, which inevitably distort and emphasise certain aspects. For someone like myself who's seen a lot of Shakespeare it's always good to see a new interpretation. I'm sorry I missed this one.
