Have just watched Patrick Stewart on BBC4 in a Stalinist setting of Macbeth.
Lots of atmospheric period settings, old newsreel footage etc.
Shame it was more towards 1950s than 1930s, but it's a cracking production.
This topic should probably be in open talk, but my first thought when I heard Macbeth with a Stalinist setting was the purges of the 1930s.
