The Weird Macbeth
"The Weird Macbeth" (formerly "Puck's Macbeth") was originally a two-part episode planned, in which several Gargoyles characters were trapped in a production of Macbeth by the Weird Sisters, before the termination of Gargoyles.  The premise was first revealed to fans at the 2001 Gathering of the Gargoyles. 
In Central Park, the Weird Sisters would have magically trapped the main cast in a production of Macbeth. It would have had Macbeth playing himself, Demona as Lady Macbeth, Goliath as Macduff, Elisa as Lady Macduff, and Hudson as King Duncan. The dilemma Goliath would face is that he had previously read the play and he would know how it ends - Macduff survives but Lady Macduff does not.  The higher-ups at Disney would not allow the episode to be made as a two-parter, and feeling that it was too complicated to fit into a single episode, Greg Weisman dropped the notion of including it in the second season of the television series.
