This series has also been referred to as X-Men: The Animated Series.
A precursor to the X-Men series was the one-shot pilot episode "Pryde of the X-Men", which aired in 1989 and focused on the character of Kitty Pryde.
Other X-Men animated projects include X-Men Evolution and Wolverine and the X-Men.
The X-Men also spawned four theatrically released feature films, the fourth of which, X-Men: First Class is a quasi-prequel to the first three films.
The X-Men made their first animated appearance in the "A Firestar Is Born" episode of Spider-Man and His Amazing Friends.
The X-Men animated series existed in the same continuity as the 1994Spider-Man animated series.
X-Men was originally to premiere over the Labor Day weekend in September; however, due to production delays, it was pushed to the end of October. The "Night of the Sentinels" two-part episode originally aired as a "sneak preview" even though it was not ready for broadcast.
Tony Daniels replaced Chris Potter as the voice of Gambit for the final three episodes of the series.
