"Learn the story of Hal Jordan and the Green Lantern."
In a universe as vast as it is mysterious, everything is possible, and for centuries there has existed a small Space Corps, very powerful, who are protectors of peace and justice, known as the Green Lantern Corps.
To know this Green Lantern Corps, via the direction of Martin Campbell, here is the movie adaptation of the Green Lantern comic. Each member of the Green Lantern has sworn to keep intergalactic peace, with powers given to them by a ring they each wear.
But, as with all action movies, evil appears with the aim of destroying the balance of power in the Universe. If you want to know if the evil Parallax achieves his aims, or if the Green Lantern Corps can stop him, you have no choice but to watch the movie. Until then you can decorate your PC with this wallpaper showing the newest member of the Green Lantern Corps: Hal Jordan.
