I don't do rehearsal. Some directors prefer to do rehearsal - readings before the actual shooting - but I don't like this process because I think there are certain things that are so spontaneous, and they cannot happen twice.
Sometimes, when you're on the streets, certain music inspires you, and then you have a vision. But, at the end of the day, it's a synthesis of visions, so you have to think, as a director, of a scene, or how to deliver a line, or how do this visually.
Some actors like encouragement. Some actors prefer to have pressure. And sometimes, for some actors, its better to give your comment by silence, because they are so skillful, so gifted, that they understand without talking too much.
I think of action as a dance. It's a riddle; it should have emotion in it.
When it's time to let go, I don't look back, and I start another project as soon as possible. One thing I remind myself is that I don't want to Photoshop my past.
It is always good to work with a very regular group of people because we know how high we can fly and what are the parameters, and it becomes very enjoyable.
