I enjoy teaching Shakespeare, and I'm always looking for ways to extend the conversation so we're not just talking about the 1500's. If I were teaching Macbeth, I'd definitely consider using excerpts of my very favorite film version of Shakespeare, Akira Kurosawa's Throne of Blood. It's definitely a classic, and you'll need to explain the conncection, but I know my seniors would really enjoy the change of setting, opening the door to discussions of how a play like Macbeth is able to transcend its origins and speak to contemporary artists.
In particular, I would draw attention to the Lady Macbeth character and Noh theatre. My students would really enjoy seeing how Kurosawa brings out aspects of her character.
