CANNES, France: Michael Fassbender doesn’t know if the “Macbeth” curse carries over to movie adaptations, but he’d rather not test it.

“The Scottish film” is what Michael Fassbender calls his “Macbeth” adaption, which is set to premiere Saturday at the Cannes Film Festival. He’s maintaining the theatrical superstition of not speaking the name of Shakespeare’s play — at least he wasn’t in an interview ahead of the festival.

“Sometimes I say it, sometimes I don’t,” Fassbender said. “It depends on the day.”

“Macbeth,” usually referred to by the euphemism “the Scottish play” by actors wary of its legendary spell, will be the final film to screen in competition at Cannes. Directed by Australian director Justin Kurzel and co-starring Marion Cotillard as Lady Macbeth, it has been eagerly awaited as the blood-soaked finale of the French Riviera festival.
