You never know what you do that could be totally out of left field, which actually might work and give something fresh to the whole scene, to the character, whatever. If you have that with a director who then knows how to shape it, either in the direction, in the moment, or in the editing, then that's good.
It's a very stressful thing, directing a movie. You have the budget, you have the schedule, you are in certain confines, and you have everybody giving you advice about what to do.
