What would happen if you say Macbeth and don't run out of the theater?

Answer 1

Assuming that you are not actually rehearsing or performing the play, just referring to it inside a theatre, be prepared to deal with a lot of grumpy actors and actresses who will earnestly ask you to stop referring to it by name.

Answer 2

In theater superstition, the play "Macbeth" is considered cursed. If someone says "Macbeth" in a theater, tradition holds that they must leave, spin around three times, and spit over their left shoulder to ward off bad luck. Failing to do so may invite misfortune or accidents during the production.
