What is the antidote to macbeths curse?

Nobody really knows. It has been speculated that Macbeth's rep as a "bad-luck play" may come from the fact that much of the action takes place in the dark, sometimes in a fog, and yet a lot of people are swinging sWords about: a recipe for someone accidentally tripping, slipping, or getting hurt with a sWord. Others think it is a reaction to the presence of witches in the play. However, although Macbeth may have been the first play of the time to have capitalized on the subject of witches, there were others, including Middleton's The Witch (1609), Dekker, Ford and Rowley's The Witch of Edmonton (1621) and Heywood and Brome's Lancashire Witches (1634), the last two of which were very successful and are not thought to be unlucky at all.

In any case, stories are told about disasters which took place during productions of the play, but since disasters during productions of any play are pretty standard, this should come as no surprise.

In any event, actors will get upset if you say the name of the play inside a theatre unless you are actually performing the play. Various strange "cleansing rituals" have been proposed to dispel the bad luck arising from saying the name of the Scottish Play. An episode in the third season of the comedy series Blackadder pokes fun in a hilarious way at these cleansing rituals.
