Roman Polanski has the capacity to shock. Amongst present day directors, Polanski has a unique eye for casual violence, stark cruelty and believable horrow. Macbeth, the darkest and most brooding of Shakespeare's tests, is vividly brough to life by Polanski in portrayal of ruthless ambition and murder. With John Finch in the title role, Polanski's MacBeth is the most chilling and terrifyingly realistic interpretation of the classic.
