I wonder if that was a case of truncation. Like sorta how they changed a bunch of things from the comics, while still using them as a base for the first TMNT movie. They had to keep April's cartoon job as a reporter because, well... if they used her scientist persona, We probably wouldn't have seen her till the second movie, end of the first at the latest. And to do her story, we'd have to have Henson manufacutr hundreds of little Mousers. Plus, for dramatic effect, Raph was the one who got knocked unconcious in the film, but Leo in the comics, leading Don to be Casey Jones's best friend... stuff like that. I half expect comic book movies to just wing it anyway. The Joker became Joe Chill for the sake of the story, seems like.Burton's entire introduction of the Joker was incorrect and Nicholson admitted that he let the makeup do most of the performance for him. I suppose that's why it was more surface-oriented. The Joker really isn't supposed to even have one particular origin nor are we ever to know his real name. But if he did have an origin, it was not as the man who killed Bruce's parents.
I blame comic book guy types for that. "No no no! That wasn't supposed to be an "an" it was supposed to be a "the" in Manhattan's speech!" Really. Batman and Spider-man movies ARE easier to make. So many people have worked on these characters, and there are so many different ways to interpret them. When you take a single graphic novel made by a single person, you pretty much have little or no room for interpretation. Especially since they tried to get things as close to the actual novel as possible, sacrificing a couple things because they fit better with the plot and time constraints.The superhero film that was over-hyped, underperformed and therefore is now underrated was last year's Watchmen. It wasn't perfect, but it is a beautiful piece of cinema that few audience members could really appreciate.
The film did seem to resonate with casual people, however. They weren't the prejudice comic fan types that wanted to pick out every flaw if they thought not seeing it, or hating it outright did Alan Moore a service. Sure, I never like the idea of a company going over the head of the creator of something (Underdog was a prime example, and they do it with musicians all the time), and I understand other adaptions of his work were meh at best (and Extraordinary at worst, if you get the reference)... but this film was pretty good. And I saw it on a crappy television.
Oh, and Sonic the Hedgehog cartoon buffs.... during a war room scene, Gary Chalk (voice of Grounder among others) is one of the generals. He gets a live action speaking cameo.
