Above, the mock-up comic book cover that Marvel editor-in-chief Joe Quesada prepared for an appearance on Thursday night's Colbert Report, where he brought Stephen Colbert up to speed on Civil War, the "Marvel Comics Event" that pits superhero against superhero to explore the permeable boundary between homeland security and personal liberty:

"Before the show, Colbert came into the green room and set the tone for me. First he gave me the warmest welcome, shook my hand and told me he's a huge Marvel fan...As he left he gave me the wag of the finger and said, 'You know how the show works?' I said, 'Yes.' He said, 'Remember, I'm an idiot,' I told him that I was one as well and then he went off to do the show."
