Interesting to think about, yet strange. Especially since he turned in a fantastic performance as The Joker in the equally fantastic "THE DARK KNIGHT". It would also be interesting to see what James Franco would have done with the role, considering he was offered the role and did audition. Much like how Cillian Murphy was offered the part of Bruce Wayne/Batman in "BATMAN BEGINS" but instead showed up as the terrific and horrifying Scarecrow. However, Maguire does the role justice, and I think he's perfect. Now that he's played him for three movies and they are planning a fourth, I couldn't imagine anyone else as the character.
