There were various differences and similarities between both the 1979 and the 2006 version of Macbeth. In similarities both movies had the same main characters and no differences between the deaths. They also both used the same diologue and had the same plot as to Macbeth killing Duncan and going mad due to paranoia and guilt.Another similarity they had was that they were both violent and Macbeth although was in gunfight still died by sword or dagger rather.
The differences between the two were recognizable from the begining. The 2006 version had actual scenery. It also differentiated in weaponry using guns instead of swords. Duncan who is a king in the 1979 version is the leader of a crime syndicate dealing drugs in the 2006 version. The witches who foretold the future are more sexual and appear to be teenagers in the newer version. Lady Macbeth in the older version wants Banquo dead. The 2006 version Macbeth is the one who wants Banquo dead and needs no persuading in doing so.
