My favorite Shakespeare is Othello and there are some good ones, the Lawrence Fishburn from the 90s is decent, and there is an Olivier floating around that is excellent. But, try the Zeffirelli version of Verdi's opera Otello for my all time favorite Iago.
Macbeth (1971). No matter how you feel about Polanski as an (alledged) human, it's quite a film https://www.imdb.com/title/tt0067372/?ref_=ext_shr. There is also a Michael Fassbinder Marrion Cottiard from 2015 that I havent seen, but am curious about.
Kenneth Branaugh did a bunch of Shakespeare in the 90's which were mostly pretty good.
If anyone can suggest a good film version of The Tempest I'd love to know about it.
