Two such superstitions float around Macbeth. The first is that it's bad luck to even say “Macbeth” except during rehearsal or performance. When referring to the work one instead uses circumlocutions, such as “the Scottish play” or “Mackers” or “the Scottish business” or “the Glamis comedy” or just “that play." Some say this rule applies only when inside a theater; it’s OK, therefore, to use the dread name in other settings – like classrooms, for instance.
The remedy, if someone does happen to utter the unutterable, is to leave the room, close the door, turn around three times, say a dirty word (or spit, some say), then knock on the door and ask to be let back in. If you can’t do all that, you simply quote from Hamlet, act 1, scene 4: “Angels and ministers of grace defend us!”
The second superstition is that the play itself brings ill luck to cast and crew, and many productions of Macbeth have, in fact, encountered unfortunate circumstances. The supposed origin story for this is that Shakespeare used “authentic” witches’ chants in the play; as punishment, real witches cast a curse on the play, condemning it for all time.

A list of incidences:
• In the first production of Macbeth, on August 7, 1606, Hal Berridge, the boy playing Lady Macbeth, became feverish and died backstage. This story is likely mythical, and further tradition says that Shakespeare had to take over the part. (One version holds that Shakespeare played the role badly, and later chewed out his fellow actors for mentioning “that play,” thus beginning the tradition of not referring to it by name.)
• In a 1672 production in Amsterdam, the actor playing Macbeth substituted a real dagger for the blunted stage dagger and killed the actor playing Duncan, in full view of the audience.
• On the opening day of a London run in 1703, England was hit with one of the most violent storms in its history.
• At a 1721 performance a nobleman in the audience got up in the middle of a scene and walked across the stage to talk with a friend. The actors chased him from the premises; he returned with militiamen, who burned the theater down.
• Female Lady Macbeths haven't been immune. In 1775, Sarah Siddons was nearly attacked by a disapproving audience. In 1926, Sybil Thorndike was almost strangled by a fellow actor. And in 1948, Diana Wynyard decided to play the sleepwalking scene with her eyes closed and sleepwalked right off the stage, falling 15 feet. In the best show-must-go-on tradition, she finished the performance.
• In the mid-1800s, two rival actors (William Charles Macready of England and Edwin Forrest of the U.S.) staged competing productions, so that on May 10, 1849, they were both playing Macbeth in New York. An audience of Forrest fans threw fruit and chairs at Macready during his performance at the Astor Place Opera House, disrupting the show and starting a riot. The militia was called in and fired on the crowd; more than 20 died and another 30-plus were wounded.
• On April 9, 1865, Abraham Lincoln was reading passages from Macbeth – those following Duncan's assassination – aloud to some friends. Within a week Lincoln was himself assassinated.
• During the first modern-dress production, at the Royal Court Theatre in London in 1928, a large set collapsed, seriously injuring some cast members.
• In a 1937 production a heavy counterweight crashed to the stage, missing Laurence Olivier, playing Macbeth, by only inches.
• In a 1942 staging, with John Gielgud as Macbeth, three actors (two witches and Duncan) died and the set designer committed suicide.
• In a Thursday-night performance in 1947 actor Harold Norman was stabbed during the final sword fight in act 5 and died of his wounds. On Thursdays his ghost is now said to haunt the Coliseum Theatre in Oldham, where the fatal scene was played.
• In a 1953 outdoor production in Bermuda, during the realistically staged attack on Macbeth's castle, a gust of wind blew smoke and flames into the audience, who fled. Charlton Heston, playing Macbeth, suffered severe burns on his groin and leg because his tights had accidentally been soaked in kerosene.
• Rip Torn's 1970 production in New York City was halted by an actors’ strike.
• David Leary’s 1971 run was plagued with two fires and seven robberies.
• In 1971 Roman Polanski (who may himself have seemed cursed at the time, as his wife Sharon Tate had been murdered by followers of Charles Manson just two years earlier) made a film version; a camera operator was almost killed in an accident on the first day of shooting.
• J. Kenneth Campbell, playing Macduff, was mugged soon after the play's opening in 1981 at Lincoln Center.
• In a 2001 production by the Cambridge Shakespeare Company, Macduff injured his back, Lady Macbeth bumped her head, Ross broke a toe, and two cedar trees from Birnam Wood topped over, destroying the set.
