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.

Superman has evolved continually in the comic books over the course of 75 years. He couldn't even fly for years in the original comic books. Kryptonite wasn't added until the '60s. All sorts of things like this. If a character is going to remain vital, he does have to change with the times.

'Skyline' is an alien invasion film that really takes an interesting look at the genre. The writers did an amazing job of creating a new take at how life from other planets come and plan to invade Earth.
