"[Insomnia]’s a film that I look back on with great fondness. Working with Al Pacino, Robin Williams and Hilary Swank was an incredible experience. Sometimes, when people look for connections in your work, they look more at things like budget level than at the filmmaking itself. If you compare it to Oppenheimer, for example, there’s a similar attempt to try and convey the subjective experience of the protagonist. In the case of Pacino’s character, he’s suffering from a distortion of perception due to lack of sleep, and it’s not a million miles away from what I’m trying to do with showing Oppenheimer’s internal process, particularly at the beginning of the film."
