Green Lantern the movie is due to release around June 2011 starring Ryan Reynolds as Hal Jordan a.k.a. Green Lantern.
For the non-avid fan of DC comics Green Lantern character, Green Lanterns (there’s a lot of them!) are basically an intergalactic police squad (the original pulis kalawakan even before Shaider!) that divided the universe into 3,800 sectors. Hal Jordan, an Earth-based test pilot, is selected by the Green Lantern Corp. to patrol sector 2814. Every Green Lantern is given a power ring that is capable of creating a quasi- energy-beam version of whatever the user desires. If Hal Jordan wants to fight crime with a giant corkscrew, the power ring will create a giant corkscrew.
