It took a while for the first 'Blade' to get made, and Marvel decided they liked the Whistler character so much, when Blade guest starred on the 'Spider-Man' cartoon, they put Whistler on the cartoon, and the movie hadn't come out yet.

'Batman Begins' came out and it was really successful, and it had gritty naturalism. And suddenly... I can't tell you how many movies I was pitched where it was, 'We want to do what you did with 'Batman' but with 'Teenage Mutant Ninja Turtles,' or whatever.
