Fun fact: When Patrick Stewart's agent told him that he was up for the role of Professor X in the X-Men movie, he knew nothing of the comic. They then handed him a copy of the comic with Xavier on the cover to which Stewart exclaimed "WHAT AM I DOING ON THE COVER OF A COMIC BOOK?!?"
Anyway, thanks for your seventeen years of service as Charles Xavier, Patrick Stewart. I remember all the way back in elementary school discussing with my friends on how cool it would be if Picard played Professor X in an X-Men movie someday.
