Theatre superstition about Macbeth on Broadway houses

A longstanding theatrical superstition holds that saying the name 'Macbeth' inside a theatre brings bad luck; actors instead call it 'the Scottish Play.' This tradition is widely observed across Broadway venues in New York City and is referenced in histories and reporting on Broadway practice. Individual theatres such as the New Amsterdam Theatre are among the Broadway houses where performers and crews follow rituals tied to the superstition. The origin and efficacy of the superstition are part of theatrical folklore and are debated.
