What would you do with the Joker in Nolan's films?
- Ignore him completely and never mention him.
- Have a passing mention.
- Have him referred to a lot.
- Using CGI techniques, take deleted scenes and/or unused vocal recordings by Heath Ledger, and with body doubles and vocal impersonations a la' The Crow, have him in the shadows and briefly seen in the film.
- Have him never seen but be a driving force of the plot.
- Any other ideas you might have.
