A movie and a stage show are two entirely different things. A picture, you can do anything you want. Change it, cut out a scene, put in a scene, take a scene out. They don't do that on stage.
“Try not to do too many things at once. Know what you want, the number one thing today and tomorrow. Persevere and get it done.”
“What to an outsider will be no more than the vigorous presentation of a conviction, to an employee may be the manifestation of a determination which it is not safe to thwart.”
