I love it when we're shooting a scene and someone stops me to give input about something and make a change because then it doesn't feel like I'm just bossing people around and I know their heart is in it.
By the time we're talking about it we could have already filmed it by now.
If your excuse not to do something is that it will "take too long" or it's "too tedious", then you need to do it anyway.
I used to wonder what the overall role of cinema is in today's society. What makes it so important? But I found it's true importance when I asked myself what the role of cinema is in my own life.
