It's no secret WB didn't really take its superhero catalogue seriously, and one day they figured they should follow into the footsteps of THE MASK, a dark and gritty C-list comic book character reinvented as a comedy vehicle for Jim Carrey, and decided to do the same, but for Jack Black, and picked Green Lantern to take the bullet.
Robert Smiegel wrote the script, in which noble warrior Abin Sur crash-lands on Earth after being mortally injured by the Green Lantern Corps' longtime enemies, the Tchkk-Tchkk, and orders his ring to find a worthy replacement. Rather than brave military pilot Hal Jordan, however, the ring settles for dim-witted IKEA employee Judd Plato, whose only accomplishment is being titled "the bravest man in America" for eating a coyote carcass on TV. Aided by his equally moronic comic book afficionado best friend Seth, a role written for David Spade, Judd goes around fighting crime, hoping to impress his longtime crush Cassandra, until he's whisked away to Oa for Green Lantern boot camp under Sergeant Kilowog, where he butts heads with stuffy veteran Sinestro and manages to woo his protege, Katma Tui. Judd soon proves his worth when he finds out Sinestro is working with the Tchkk-Tchkk to take over the universe and rallies the Green Lantern Corps to stop them.
However, to WB's surprise, way more people cared about Green Lantern than The Mask, and the internet gave them a voice, albeith a still rudimentary one. With not a lot of interest in Hollywood in the project, it died a quick and painless death.
