I'll begin with a confession: I loved Heath Ledger's portrayal of the Joker in the Dark Knight to nearly obsessive dimensions. For this reason I was devastated by the loss of Ledger and the reality that no future Batman movie could ever be the same without his presence. I always imagined what the unwritten script for Joker would have been like in Nolan's second film, captured in Arkham asylum, being introduced to the intern psychologist Harley Quinn (based on DC comics canon).
In brief: I want someone who feels ambitious enough to portray Harley Quinn. I do not want DC Comics Quinn, I want a much more dark and imaginative version; a complex, psychotic, fich and vibrant mess of a woman, who nevertheless possesses the intelligence to have become a doctor in psychology (before being seduced by Joker). I want a Medusa of a woman (or dare I ask -- a Medea?), with all your powers of creativity, ingenuity, and care.
Anyone with any interest please contact me. But first I recommend reading some of my posts and being somewhat familiar with my writing style.
