Justice League is an American animated television series which premiered on Cartoon Network from November 17, 2001 to May 29, 2004. The show was produced by Warner Bros. Animation. It is based on the Justice League of America and associated comic book characters from DC Comics. Animator Bruce Timm, who helped make Batman and Superman into popular animated series in the 1990s, took on the challenge of adapting the Justice League comic book and turning it into an animated sequel to his two former animated series.
This new animated TV series brought all sorts of new characters. Ignoring the sidekicks, pets, and other elements of the earlier Super Friends series, the line-up of this new JLA adaptation was created with two things in mind: to pay tribute to the original line-up of the Justice League of America while also reflecting racial and cultural diversity. Significantly, the well-known superhero Aquaman was left out of the lineup (although he would become a member of the team on Justice League Unlimited), and was replaced by Hawkgirl, the team's second female (along with Wonder Woman). Additionally, John Stewart -- an African American Green Lantern, who had previously worked with the League in the comics -- was used rather than one of the better-known modern-era Green Lanterns: Hal Jordan, Guy Gardner or Kyle Rayner (even though Rayner had appeared as Green Lantern in Superman: The Animated Series). In addition to his African-American heritage, the producer felt Stewart's original abrasive personality would have more dramatic potential. In the second season, Rayner is described as a Lantern in training under Stewart's old mentor, explaining his absence. Both Rayner and Jordan make brief appearances in Justice League Unlimited.
The show met with significant success, partially due to loyal fans already familiar with these incarnations of the characters, and partially from a new generation of viewers. The two-part nature of most episodes led Cartoon Network to choose to air the episodes back-to-back. According to audio commentary on the DVD release of Season 2, the second season finale "Starcrossed" was expected to be the final episode of the series. However, in February 2004, Cartoon Network announced a follow-up series, Justice League Unlimited.
The series was acknowledged in Cartoon Network’s 30th Anniversary video in October 2022.
