This 1976 Royal Shakespeare Company production of Macbeth was originally broadcast on Thames Television in 1978. The company's artistic director Trevor Dunn directs the cast on a small bare stage with mostly black costumes and minimal props. After the witches (Susan Dury, Judith Harte, Marie Kean) announce the prophecy that Macbeth (Ian McKellen) will be the next king, the elderly King Duncan (Griffith Jones) proclaims that his son, Malcolm (Roger Rees), will be heir to the throne. Lady Macbeth (Judi Dench) learns about the witches' prophecy in a letter, prompting he to ask the gods to remove her femininity so she can make her weak husband kill the king. When Duncan comes to visit Macbeth's castle, he is murdered in his sleep. Macbeth kills the guards, claiming they were the murderers. In fear of their own lives, Duncan's sons flee the country and Macbeth is crowned King of Scotland. Riddled with guilt, Macbeth goes mad and sees horrible visions while the witches announce the prophecy of his downfall. Also starring John Woodvine as Banquo, Ian McDiarmid as the porter, and Bob Peck as Macduff.
