Alright, so it's not true, but the similarities are uncanny. I can't believe I've never noticed before, or that this hasn't been suggested before, but I believe Joseph Gordon Levitt would make a great successor for Heath. I mean physically, their characteristics are very, very close (See compilation of images below. 1.)JGL; 2.)Heath Ledger, Joker prosthetics, no makeup; 3.) JGL w/mock-up of scars and makeup) Plus they've worked together before (see 10 Things I Hate About You [great movie!]) and JGL has been moving up in the movie world as of late. I think he'd honestly do a very good job. Other opinions?
