I am one of many who enjoy the batman series, and feel that James Franco would be the best choice to play the Joker in an (multiple?) upcoming movie(s). Our reasoning is that Mr. Franco, as evidenced by his writing and past acting in films such as "The Interview" and "I Am Michael", can, quite simply, be insane at times. Also, he has a near-identical facial structure to that of Mr. Ledger, if that is factoring into your decisions.
