the hook for me. i put it in tenet, referred to it there. and actually when when we wrapped that film, rob pattinson, who's in that film, he gave me a book of oppenheimer�*s speeches from the 19505, where oppenheimer is giving a series of speeches, really wrangling with the consequences of this technology that they've unleashed on the world. and it's such a compelling thing to imagine to be with this person, with his fellow scientists, trying to reckon with the consequences of unleashing atomic power on the world. we knew the world would not be the same. few people laughed. a few people cried. most people were silent. and what's your sense of him as a man and how he did deal with what he had created?
