Christopher Nolan has revealed that he sneaked his mother, his wife and three of their children into the back of an IMAX theatre in New York on the opening night of his film Oppenheimer.Speaking to Variety, the director explained that he wanted to experience the authentic reactions of a paying audience to his film at the AMC cinema in Manhattan’s Lincoln Square.“I usually don’t want to go,” Nolan said, “But the minute I’m there, something magic happens.”Nolan continued that he felt the tension rise as the film built towards the first detonation of the nuclear weapon assembled by the film’s titular protagonist. “It was a remarkable experience to be there,” Nolan reflected.
