Most people don't see Hamlet as an old bald guy.

I am a huge fan of what Marvel has established. But when they first came to me, Thor and Captain America were not even close to being finished. I thought to myself, 'Okay, you have all these moving parts, but how can you possibly bring them together?' Iron Man, Hulk, Thor and Captain America don't seem like they could co-exist, and ultimately that is what intrigued me and made me think, 'This can be done and this should be done.' You can't put these characters in a movie together without a certain amount of humor. It's an inoculation against the unreality.

I don't have a particular ambition in any medium. I just want to keep telling stories. If somebody pays me, also good.

You do not want a war. You have known violence, you have suffered loss, but you have seen nothing of war. War is not just the business of death; it is the anti-thesis of life. Hope, tortured and flayed, reason, dismembered, grinning at its limbs in its lap. Decency, raped to death... You will be a murderer and more.

A great scientist is more open to a new idea than almost anybody.

Actors wait tables, directors work at video stores.

I never tire of the heroes that I knew growing up.
