The long-awaited day is here! US Congressman and civil rights icon John Lewis' first graphic novel with Andrew Aydin and Nate Powell, March: Book One, is in stores everywhere... even in e-book form.

And what better way to launch than with a funny and inspirational interview with Stephen Colbert on Comedy Central's smash hit The Colbert Report?

The two legends discussed the 50th anniversary of the 1963 March on Washington (where John Lewis was the youngest person on stage and Stephen Colbert was the youngest fetus in the audience), as well as new challenges ahead for voting rights in America, and of course the new graphic novel trilogy March.

To Stephen's joke about a comic book cheapening the dignity of the civil rights movement, Congressman Lewis pointed out that a 1957 comic book, Martin Luther King and the Montgomery Story, was a significant influence on his generation of activists, and is now an inspiration for March. "So meeting Dr. King was like meeting Superman!?" Hard to argue with that, Stephen.
