The most commonly held taboo in the arts is uttering the word "Macbeth" inside a theater.

Shakespeare's tragedy was cursed before its first performance more than 500 years ago. Since then, the superstition forbids the show's title to not be spoken inside of a theater, instead, it's referred to as "the Scottish play."

Before taking the stage for opening night of the Broadway revival on Thursday, Daniel Craig and Ruth Negga were more brazen, preferring not to buy into the superstition of theater's unspoken word.

The James Bond actor, who stars in the titular role, says he doesn't worry about that sort of thing. Nor does he abide by any of the ways of undoing the curse, like walking in circles outside the theater and waiting to be invited back inside.

His co-star was even brasher.

"I don't think that's going to affect it too much to see regret. But talk to me in three months," Negga said, referring to the end of the play's run.

In Shakespeare's time, women didn't have a place in the theater as the female roles were played by men. Legend has it that the male actor scheduled to play Lady Macbeth died unexpectedly before the play's first performance.

While Craig and Negga hold a looser attitude when it comes to the Macbeth curse, Maria Dizzia, who plays one of the witches, wondered if they were truly left unscathed, saying "We said Macbeth, and then we all got COVID,"

And director Sam Gold expressed second thoughts.

"I'm not a superstitious person, but this process will teach me to be one the next time. I definitely said the word Macbeth a lot and everyone definitely got COVID," Gold said.

It's important to note that "Macbeth" was not the only show that had a shut down due to COVID.

"The Music Man" had a string of canceled performances after a COVID-19 outbreak. Other shows affected in some way, included "Hadestown," "Dear Evan Hansen," and "The Lion King."
