Macbeth vs Polanski

Shakespeare version of Macbeth and Polanski movie of Macbeth. The films ending is kind of different from that of the play. I think that the director of the play wanted to have the guests thinking. Even though Malcolm is crowned as Scotland's rightful king his come to an end speech is discarded in favour of an abrupt wordless scene showing his brother Donalbain returning from the exile. Throughout the entire story, Donalbain is shown as being jealous of Malcolm, as it maybe even more so than Macbeth was the jealous one. The ending as a result recasts the story as a closed boundary of action suggesting that the tragedy will be repeated again.
