CANNES, France (AP) — Michael Fassbender doesn't know if the "Macbeth" curse carries over to movie adaptations, but he'd rather not test it. "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, which concludes Sunday with the presentation of the Palme d'Or top prize.
