Re: James Cameron's Spider-Man
Well, here's something that some of you may or may not find cool; Cameron initially started talking to Marvel, not to make a Spidey film, but to make an X-Men film.
Imagine if Cameron had been second unit director on Singer's X-Men films, i.e. shooting the action for him (we all know Singer didn't do it himself).
There is no Marvel/DC rivalry. Most of the great comic creators worked for both; Jack Kirby, Frank Miller, Grant Morrison, Walt Simonsen, Gil Kane, Steve Ditko, John Byrne, Steve Englehart, Mark Waid...even Stan Lee.
