No offense, but is there really much to do with this part? I've seen many interpretations and actresses and it's barely a walk on in my opinion. I think Morrible is only truly effective in her speech before Defying Gravity most actresses crap the bed on that one. The only person I was who was truly chilling was Alma Cuervo.
I don't know why the spend the money to stunt cast this part.
