About Marvel Studios' "Captain America," he stated the following:
It's not going to be a Captain America that you expect. It's something different. It is influenced by the comic book, but it goes off in a completely different direction. It's the origin story of Captain America. It's mostly period—there are modern, present-day bookends on it—but it's basically the story of how Steve Rogers becomes Captain America. The great thing about Captain America is he's a super hero without any super powers. Which is why this story, among the hundreds of super hero stories, appealed to me the most. He can't fly, he can't see through walls, he can't do any of that stuff. He's an every man who's been given this amazing gift of transformation into the perfect specimen—the pinnacle of human perfection. How does that affect him? What does that mean for him emotionally and psychologically? He was this 98-pound weakling, he was this wimp, and he's transformed instantly into this Adonis. You'd think he got everything he wanted. Well, he didn't get everything he wanted. The rules change at that point and his life gets even more complicated and dire. For me, that's the interesting part of the story. It's got some great action sequences in it and some incredible stuff that we've never seen before. But at the heart of it, it's a story about this kid who all he wants to do is fit in. This thing happens and he still doesn't fit in. And he has to prove himself a hero—essentially go AWOL to save a friend...
Well, there is going to be a Jurassic Park IV. And it's going to be unlike anything you've seen. It breaks away from the first three—it's essentially the beginning of the second Jurassic Park trilogy. It's going to be done in a completely different way. That's pretty much all I can tell you.
