Do You Have a Foundation of Reality on Set?

Most directors want to have a basis of reality or as much basis of reality on set as possible, don't they, even when they're doing CG? I mean, it seems normal in my experience. It wasn't until the production that I just finished, which was Fast and Furious number nine of all things, which I had the pleasure of working with the most wonderful supervisor, the effects supervisor of Peter Chang. The most, he had a gift of being able to explain why he wanted or needed the things he did. To me, it was to you perhaps completely obvious and you have to have.
