This was filmed in 1979 as a recreation of a successful theatrical production by the Royal Shakespeare Company ca. 1976-1977. It stars (Sir) Ian McKellen and (Dame) Judi Dench as the Macbeths. McKellen looks shockingly youthful for those used to seeing him as Gandalf in the Rings franchise. Check this out:
This production has virtually no props and relies on Shakespeare’s words as delivered by the thespians. McKellen is brilliant, the supporting cast is too. Dench is good, especially in the sleepwalking scene… perhaps too maternal and nice-seeming to be the diabolical Lady M. This is a truly minimalist production. I loved it.
Grade: A for brilliant performances all-around
