X-Men: Pryde of the X-Men (1969) on Netflix

Pryde of the X-Men was a short-lived series about the X-Men, with the main character being Kitty Pryde (whose alias is Sprite, though she never becomes Sprite in the series, but rather in Spider-Man and his Amazing Friends), which is why the series is titled Pryde of the X-Men. The show was produced by Marvel Productions and Sunbow Productions, who made a pilot for NBC. The pilot aired, but for unknown reasons, it was never turned into a full-blown series. Despite it not becoming a full series, the pilot has aired in syndication, and was later released on video.
