Christopher Nolan does things his own way. That’s led to some of his greatest technical coups to date; when he wanted to defy gravity for Inception, he built a giant rotating box the size of a hallway. Armed wth the biggest budgets studios can afford, he employs new technologies and puts them fully through their paces, all to bring his massively ambitious visions to life. And for his latest epic Dunkirk, Nolan wanted to blaze his own path yet again. But this time, his plans didn’t involve fancy equipment or elaborate sets.
