The film begins with the death of Abin Sur (Temuera Morrison), a member of the Green Lantern Corps, who crash-lands on Earth. Before succumbing to his injuries, Abin Sur’s power ring seeks out a worthy successor, choosing Hal Jordan (Ryan Reynolds), a reckless and skilled test pilot.
The climax of the film occurs as Hal is transported to the planet Oa, the home of the Green Lantern Corps. There, he meets Tomar-Re (voiced by Geoffrey Rush), Kilowog (voiced by Michael Clarke Duncan), and other Lanterns who inform him about the Corps and their mission to protect the universe from the fear-driven Parallax (voiced by Clancy Brown).
Back on Earth, scientist Hector Hammond (Peter Sarsgaard) is exposed to alien material from Abin Sur’s crash, gaining psychic powers and becoming increasingly malevolent. At the same time, Hal struggles with his newfound responsibilities as a Green Lantern and doubts about his worthiness.
The movie features a climactic battle between the Green Lanterns and Parallax, who feeds on fear. As Parallax begins to threaten Earth, Hal, with the support of his fellow Lanterns, must overcome his fears and use the power of will to defeat the cosmic entity.
The film explores themes of overcoming fear, embracing one’s true potential, and the responsibility that comes with great power. It also delves into Hal Jordan’s personal growth as he learns to harness the power of the Green Lantern ring.
“Green Lantern” received mixed reviews from critics, with praise for its visual effects but criticism for its plot and character development. Despite the mixed reception, the film attempted to launch a franchise, but plans for sequels were ultimately scrapped.
