Green Lantern is a 2011 American superhero film based on the DC Comics character of the same name. The film stars Ryan Reynolds, Blake Lively, Peter Sarsgaard, Mark Strong, Angela Bassett and Tim Robbins, with Martin Campbell directing a script by Greg Berlanti and comic book writers Michael Green and Marc Guggenheim, which was subsequently rewritten by Geoff Johns and Michael Goldenberg. The film tells the story of Hal Jordan, a test pilot who is selected to become the first human member of the Green Lantern Corps. Hal is given a ring that grants him superpowers, and must confront Parallax, who threatens to upset the balance of power in the universe.
Billions of years ago, the Guardians of the Universe use the green essence of willpower to create an intergalactic police force called the Green Lantern Corps. They divide the universe into 3,600 sectors, with one Green Lantern per sector. One such Green Lantern, Abin Sur of Sector 2814, defeats the malevolent being Parallax and imprisons him in the Lost Sector on the desolate planet Ryut. In the present day, Parallax escapes from his prison after becoming strengthened by an encounter with crash survivors who had accidentally fallen into the dugout where Parallax was imprisoned on the abandoned planet. Parallax feeds on their fear to gain strength before pursuing and nearly killing Abin Sur, who escapes and crash-lands on Earth where he commands his power ring to find a worthy successor.
