Good! They may have to write something in the script about the Joker being held in Arkham's lowest reaches, but only in reference. This generation should not see another Joker.
I think he makes at least a cameo. I made the last film. They would be foolish not to play off his role if he were still alive.
Ledger had signed a 2 movie deal and I think I remember reading an article that there were originally plans for The Joker to return for the 3rd film.
I completely agree. I'm glad they're not bringing back the Joker. It would've been lame as hell to have somebody try to fill Ledger's shoes. Let it be for the next 15-20 years.
