After Oppenheimer I realized that Christopher Nolan is only able to make one movie. That movie is a movie about a damaged man who must find the solution to something and he is special in some way which either will allow him to find it or demonstrate that no one can. Which made me think about who does Christopher Nolan see himself to be in all these films? The protagonist? Maybe this is all critical nonsense.
Complex men suffering is not unique to Nolan (e.g., king Lear). He simply seems to be able to create compelling versions of that theme. But actually I'm wondering what would be different if there was creative boundaries on Nolan and what he would create instead.
