Like many characters in the director's comic book adaptations, Burton's interpretation of Batman's most famous nemesis The Joker, under went a slight origin overhaul.
Starting out as a key gangster called Jack Napier, The Joker comes into being when he is disfigured in a confrontation with Batman in a chemical factory.
Tim Burton Touch:
Burton's version of The Joker is strongly characterised by the way he views himself and his crimes as a performance.
The very moment The Joker is revealed he is accompanied with unsettling carnival music and he sets about engaging in an energetic, celebratory killing dance.
This is also a prime example of Tim Burton's ongoing association of villains and fun music.
Note also the art gallery attack - which firmly establishes the Bat-villain as a performance artist gone wrong, whilst Prince plays from a boom box.
