The scenario (i think) was a group of actors getting ready for to perform a Shakespearean play and one of the female actors falls back in time to encounter the "real" characters of the play, and the witch. The show was full of special effects (like the moving busts on the walls). If anyone recalls the exact storyline or details, please feel free to correct me.
In my opinion, it was a great show and nothing that has been in that theater since has topped it. It perfectly fit the theme of the park and was something truly unique. (unlike the "4D" movie/effects show that every park has now in place of a real live show)
I, for one, would love to see the park bring that show back.
