Green Lantern: Emerald Knights is a direct-to-video animated superhero film that tells various stories featuring members of Green Lantern Corps, including Abin Sur, Laira, Kilowog, and Mogo. It was released on June 7, 2011. While not a direct sequel to First Flight, the film uses the same character designs and includes a cameo by Ch'p, who had a speaking role in the previous film.
It is the eleventh film released under the DC Universe Animated Original Movies banner. It is also the second DC Animated Movie following Batman: Gotham Knight to feature an anthology format, though unlike the latter, it features a single, uniform animation and visual style and an overall linking story. The film received mixed-to-positive reviews with many critics praising the animation, voice acting, and action sequences, but criticizing the story and characterization.
Two of the stories ("Mogo Doesn't Socialize" and "Abin Sur") were based on comic stories written by Alan Moore, who has a standing policy of not allowing his name to be used in the credits when his stories are adapted to other media. Although it uses the same name, it has no relation with the 1998 comic book Emerald Knights.
Despite the film's standalone nature, Nathan Fillon would later reprise the Green Lantern role in various DCUAOM films, including the continuity-shared DC Animated Movie Universe.
