The link provided by Colt does have a lot of great information even if he did rant a little his rant brought up alot of good points that so many other haunts forget and wind up taking their guests out of the suspension of disbelief. Lots of good information on the thread. Only thing I might add is remeber you are one part of a team and your building to a crecendo. it is important you make them really think they are they and that makes the them easier to scare for the next scene. Remember to listen to the owner for they want and try diffrent techniques and styles until you find the one that works for your character. What I tell our new actors is make me think your really that character with out make up and costume and when you have that stuff you will then be an unholy terror. My biggest advice s really stay in your postition and be ready at all times.
