What I Want to Know About my Topic

I would like to know how they manage to have a medical staff on hand if something happens to one of the stars. How often do they get hurt? How severe are the injuries? What are some of the safty featuresthe producers have for there actors? When they get hurt, what do they do to handle it? Do they get another actor to do their part? When the actor gets out of the hospital, do they still get credit for the movie or TV show? How much money do the actors get paid for hurting themselves on purpose?
