No one seems to know - not even the man who came up with the script. When asked in an interview what the plot was, Sam Hall said that he couldn't remember anything about it. And if the plot was actually such that he couldn't even remember it, perhaps it's a blessing that it was never made...
even when Burton has delivered the completed movie with its post-production, there could be a SUBSTANTIAL wait before the studio shoehorns it into one of the hot release weekends on their calendar.
I would be surprised if at the very least Sam had not done a story/treatment for "hoDS 2" figuring from his experience with DC that at some point DC would turn to him and say, "OK, can you get the script to me for the new movie by the end of the week?"--and if he had some ideas, he'd want it covered. As a sometime writer myself, I know that's what I would have done in his shoes.
i know & it's just plain damn stupid if ya ask me. why wait a total year after a film is done?
If Sam said it in the 80s that sounds more verifiable to me
