Somewhat off topic now, but Nolan is fairly famous for being intricately involved with every aspect of the films he directs. He's constantly behind a camera checking out what shots are going to look like, pushing the limits of where you can put an IMAX camera, and coordinating with set builders to do ridiculous stuff like building a reproduction harbour jetty.
I do say that, too. But I'm not in the film industry. My understanding is that those who are, don't use words as crude as "made" to describe a role in the making of a film. I believe they say that he wrote, directed or produced a film.
We are not talking about some other field of expertise here, where we are outsiders – the production of food, the supply of water, or the making of movies – we're talking about our own field of expertise.
