Cameos: In the ski lodge, Mary Jane Watson can be seen drinking from a mug with a spider web on it, and Dr. Strange and Clea are standing by the window.
The story editor liked this episode best because he felt that the religious themes made the episode weightier than the network usually allowed.
Wolverine claims "[Gambit] doesn't break a sweat against Apocalypse or Magneto." Actually, Gambit never even faced Magneto in the show - the only episodes where the X-Men face Magneto were Enter Magneto (1992) and Deadly Reunions (1993), and Gambit was absent from both of those episodes.
Debut: Nightcrawler/Kurt Wagner.
Adrian Hough, who provides the voice of Nightcrawler, also played Jean Grey's father in X-Men: The Last Stand (2006).
