For the love of God, KEEP J.K. SIMMONS as J. JONAH JAMESON!
Simmons absolutely became the curmudgeonly newspaper publisher in the first three Spider-Man movies, and I don't wanna see anyone else ranting about "That Wall-Crawling Menace!" in future outings. Jonah isn't that major of a player in the story anyway, so why try to shoehorn in a new actor? I liked all three of the Spider-Man movies, though all three were flawed in different ways. Tobey Maguire made a decent Spider-Man, but I never really was sold on his Peter Parker, and Kirsten Dunst really got on my nerves by the third movie, so her MJ won't be missed. I've heard about the sparkly vampire kid being bandied about for Spidey, as well as that Arrested Development young'un, but I'm guessing they'll go with even newer young up-and-comers that I've never heard of to fill those roles in the new film. Whatever they do, let me be perfectly clear:
Future Spider-Man movie director, KEEP J.K. SIMMONS as J. JONAH JAMESON!
