I teach grade 10 in Saskatchewan. A part of our curriculum is this play. Other Shakespearean plays taught in my school are "Romeo and Julliet" and "Hamlet", both of which have decent popular movies and other content to use.
I find Macbeth has very little that engages the students besides audio. I do use Rocketboom as a help for struggling students.
Any suggestions on some additional material or a video of Macbeth that is not Polaski's version but of that calibre?
