I know this movie is old and I haven't read the comics much back then, but something I always wondered.
1.) Was the story originally made just for the movie or did they base it off a story from the comics?
2.) So, did the events that took place in the movie, is it considered an official part of the HUGE Batman saga or just a what-if story?
3.) I know the movie doesn't explain it, but what became of the Joker after the ending? (If it was explained elsewhere or just any good ass guesses?
Thanks in advance.
