I had no plans to be a director.
I am intrigued enough to want to continue, and also to try and work with companies like Sony on modifying the cameras and making them more user-friendly and efficient.
Then I became interested in drama, and almost by accident, I drifted into film.
You make sure that there's a structure that's interesting for them to play on top of, then do temp versions and try it on the film. By the time the players come to the recording session, I've found what works. So I'm not wasting their time.
