A superhero's catchphrase should be like a really memorable advertising slogan. It sticks in your head and you can't stop humming it. And let's face it, superheroes are just really selling themselves as products.

You always exaggerate things in a movie. If it makes a good visual and it excites the kids that's good.

I've written so many things over the years that I don't want to go back to being just a scriptwriter. I'm in what I consider to be the enviable position of all I have to do is come up with the idea and write an outline that makes it seem like it's a viable idea that will interest people, and then other people write the scripts -- and I become the executive producer or the producer, depending on how much involvement I have, and I get a creative credit and then move on to the next project.

I didn’t write 'Guardians of the Galaxy.' I’m not even sure who they all are. I can’t wait to see the movie.

The purpose of this is not show that I can do it better, because I think Superman is perfect. The original creation of Superman nobody could have done that better and I think Batman is pretty much a perfect character... The same with all of them. I'm just going to try to find a way to say, "If that wasn't the original idea, what would be another way to do it that would be more in my style?".

Life is never completely without its challenges.

From 1940 to about 1960, I had been writing just regular comics, the way my publishers wanted me too. He didn't want me to use words of more than two syllables if I could help it. He didn't want me to waste time on worrying about good dialogue or characterization. Just give me a lot of action, lot of fight scenes.
