Michael C. Hall for The Riddler in Batman 3

Christopher Nolan, the director of the previous two and most recent Batman films (Batman Begins and The Dark Knight), is currently on work in post-production with his latest film, Inception. I am a huge fan of Nolan's work and I, like most of the movie buff's out there, want to know more about the development of the latest Batman feature. As of right now, Christopher Nolan has signed on to direct the third installment, while his brother who has previously co-wrote the last two is set to pen the script again with David S. Goyer. I have heard word that this film with complete the trilogy and will end the story Nolan has created in a concluding fashion instead of leaving any open story plots for future sequels. This is all fine with me. Why not create for yourself your own trilogy and complete it successfully at your own terms? Peter Jackson got to do it with Lord of the Rings, Francis Ford Coppolla did it with The Godfather Trilogy (arguably with the third one being a let-down), and so why can't Nolan with Batman?
SPOILER ALERT for those of you who haven't seen the Dark Knight....oh who am I kidding, everyone has.
The Dark Knight ended with Heath Ledger's Joker getting taken into custody (or so it seems) and Aaron Eckhart's Two-Face falling to his death. Thats all fine, except Nolan had planned on having Ledger back for the third film. Circumstances have it, this is indeed not possible and Ledger's Oscar winning performance is widely regarded as one of the best acting jobs for a villain in recent memory. So what to do now? Well the worst thing Nolan could do is have a new actor play Heath Ledger's Joker. No one wants to see this character be hacked down by someone copying the late actors brilliant work. So a new villain must take on the caped crusader. I personally feel Catwoman would be a great addition seeing how Rachel Dawes, the object of Bruce Wayne's affection in the previous films got blown to kingdom come by the Joker. Catwoman would be a great love interest and side-plot character done less like the Halle Berry incarnation and more like the Michelle Pfeiffer one. What a great dark place to take Batman's character and have Bruce Wayne further loose himself in his mask by having Batman fall in love instead of Bruce Wayne! But there is one character that needs to be included in the new Batman film.
The Riddler. He would be perfect for this film. Gotham could presumably be recovering from the Joker's attack and with Batman as their current villain, the script would be smart to have the Riddler pop in as an almost "Jigsaw"-esque terrorist that leaves riddles around town and cause Batman to come back as the hero the city needs. But who could play a darker version of the Riddler? It would have to be an actor completely different from Jim Carrey to give the audience a completely different experience than the one they had with the Riddler in Joel Schumacher's Batman Forever. The web was a-buzz when Johnny Depp's name was dropped around by the likes of Michael Caine and Gary Oldman. Depp is one of the best actor's of our time and would fit this role well, but I believe he is too big a name for this kind of part. Someone would have to be different enough from Heath Ledger's Joker and not live in his shadow, while also not being big enough a star to take away the limelight needed for Christian Bale in his final performance as Batman. So I nominate....
Michael C. Hall! He's perfect and I implore anyone to argue with me about this. Why hasn't anyone mentioned this before? If he gets casted, I would have called this before anyone else I know and that will make me feel even happier (but that's beside the point). If anyone has seen the show Dexter, Michael C. Hall plays the role of "America's favorite serial killer", Dexter Morgan. Dexter balances a family, his job as a blood-spatter analyst, and his urge to kill people. He only chooses to kill murderer's, however, which gives him enough of a code to get away as the hero of the Showtime series. Hall has given award worthy work with his dark nature, soothingly creepy narration, and hilariously disconnected style with the rest of humanity on the show. He would be perfect taking on the dark knight, Christian Bale. Can anyone think of someone better?
