While the links are part of what I wanted, and appreciated, my main question has never really been answered. Are there any musical theater Experts on the site who could help me?
To recap, here are the questions I would like to have answered:
-What are the goals in a workshop that don't get accomplished by just rewriting it?
-What about benchmarks? Are there specific things I should watch out for?
-How long should I spend in workshop and how will I know when its been long enough?
-What should I look for in casting the workshop is it just actors are strong at improv or do I need to make sure they fit the role in other ways?
-How much do I listen to actors input and if they make stuff up that's included in the final script, is there any kind of credit I need to give or is that considered part of 'workshopping'?
-I know I can do whatever I want, but If I cast an actor in the workshop is it CUSTOMARY that they will expect to be cast in the staged production or is that viewed as separate project?
-I realize that many of these questions are highly subjective, but if I could get these details and the logic used behind them from a Experts experience, I can always extrapolate my own version of the process out of them with greater confidence.
