"Eric & Julia Lewald: While we’re proud of many of the episodes, I think adapting “Days of Future Past” and “The Phoenix Saga” for television were among the biggest challenges, since X-Men fans had preconceived ideas about these classics. The pilot story, “Night of the Sentinels,” was a real challenge, since we had to introduce this strange world to an audience, 90% of whom knew nothing about it. “Nightcrawler” dealt with faith in a way we’d never seen on Saturday Morning TV. And “One Man’s Worth,” my favorite of our dozens of original stories, was so satisfying that Marvel used it later as the basis for “Age of Apocalypse.”"
