The only job that was ever of interest to me other than filmmaking is architecture.

No, I've only ever done one film at a time.

I think there are advantages to different scales of filmmaking. You wouldn't want to do just one thing.

The best actors instinctively feel out what the other actors need, and they just accommodate it.

Superheroes fill a gap in the pop culture psyche, similar to the role of Greek mythology. There isn't really anything else that does the job in modern terms. For me, Batman is the one that can most clearly be taken seriously.

But 'Memento' was so successful, such a huge cult hit, almost on the scale of a large film. If that had happened, with all the acclaim, before the next job, I'd have found it very difficult to figure out what to do next.
