20 Things You Didn't Know About Christopher Nolan
15. He Only Lets Select Crew Members Read His Scripts
Nolan is one of Hollywood's most secretive filmmakers, clearly relishing the preservation of surprises until the audience is sat in the cinema watching the film for themselves.
Though it's not uncommon for blockbuster scripts to be printed on impossible-to-copy paper, Nolan has frequently gone above and beyond to ensure his sets are tight, spoiler-free ships.
For starters, when casting major roles the actors in question are typically locked in a guarded room on their own to read the script, and in the case of Kenneth Branagh in Tenet, Nolan even surprised the actor at his home, hand-delivering the script personally.
While it's common for most key crew members to have a copy of the script, Nolan insists upon only the most vital crew doing so, to the extent that while filming Dunkirk, only 20 of the 600 crew members were given access to the script.
Even Dunkirk's art director didn't get to read the screenplay until the movie was already six weeks into production, which says a lot about how fiercely the director guards his storytelling secrets.
