All of my actors are volunteers because I run a haunt at a University so I get student volunteers. In fact most of my crew is volunteer. What are some things that I can do to a.) Help my actors get into their roles and take their jobs seriously and b.) Reward them at the end of the week (we run our haunt for a week)? I can't afford to pay them which is why I use student volunteers but I want to do something to let them know I appreciate them. I also want to help them learn how act their parts more effectively.
