Green Lantern: The Animated Series is an American computer-animated television series based on the DC Comics superhero Green Lantern. The series aired on Cartoon Network, as part of their "DC Nation" television block. A one hour sneak peek aired on November 11, 2011. It ran from November 11, 2011 to March 16, 2013, with a new episode airing every week. A special screening of the first episode was shown at New York Comic Con 2011 on October 15, 2011. This was the first Green Lantern television series and the first CGI DC/WB series. The series was cancelled after one season due to poor toy sales from the live-action movie, and because Cartoon Network wanted to emphasize new shows in its "DC Nation" block.
The series focuses on the adventures of Hal Jordan, the Green Lantern of Sector 2814, and his partner Kilowog. Hal Jordan travels to "Frontier Space" the region of space at the edge of the Guardians' territory, where Green Lanterns are being picked off by the Red Lanterns. Atrocitus, their leader, wants revenge for the destruction of his world by the Manhunters, the now-decommissioned android enforcers of the Guardians. After defeating Atrocitus, Hal and Kilowog adopt Razer, a maverick Red Lantern into their fold. Their next great threat is the Anti-Monitor, who seeks to literally consume the Universe.
In early stages of production, the show was conceived as a "Bruce Timm-does-CG-project". Phil Kent, chairman and CEO of Time Warner's Turner Networks unit, originally announced that Green Lantern: The Animated Series would be a part of Cartoon Network's original programming. A preview of the show was featured at the 2010 New York Comic Con featuring test footage, characters/story description, and art work. Bruce Timm, who produced the entire DC Animated Universe, also announced at New York Comic Con that he'd be producing the show. Timm was originally was reluctant to use CG instead of traditional animation, but eventually came around. A total of 26 episodes had been ordered for the first season. By the time of New York Comic Con, thirteen had already been planned, and five had already been recorded. The series is not intended to be an origin story, due to Warner Brothers already releasing a film based on the characters' origin. The series is the first television series by Bruce Timm and the first series featuring Green Lantern to be rendered using CG. The producers have confirmed that it was requested that the character Sinestro not be used. This was later overturned in 2013, when Sinestro finally did appear. The producers also confirmed that if the series was a hit, other Lanterns like Guy Gardner, John Stewart and Kyle Rayner might be introduced.
