What's wonderful about film is that it's precious. You know it will run out. So, on each and every take, there's more focus and concentration than on a digital shoot, when the cameras keep rolling. It's like the moment the curtains come up at the theatre, and actors and the crew know they have to be ready. This feeling filters to everyone. It makes the set a really dynamic place to be. Everyone leans in to make sure they get it right. You can see it in faces and body language.
