My obsession with The Joker began 25 years ago with Jack Nicholson and his acid flower, hand buzzer and stupidly long gun barrel. In the 60's show Cesar Romero was a genius. Then we had the twisted side reimagined by Heath Ledger years later. Three very different actors, one unmistakable character. Not forgetting Mark Hamill as the voice of the Joker over 25 years and the stacks of talented writers and artists who have created dozens of my favourite books. Everybody ever needs to have read 'The Killing Joke'. With such a multi-faceted character, comic fans have never been so spoiled for choice. And nobody is safe. Ha. Ha. Ha.
