The Green Lantern (2025) teaser trailer opens with a sweeping shot of the cosmos, showing various alien planets, nebulae, and interstellar phenomena. A voiceover from the Guardians of the Universe speaks cryptically about the power of the Green Lantern Corps: “In brightest day, in blackest night… no evil shall escape our sight.” The camera zooms in on Oa, the home of the Green Lanterns, where we see legions of Lanterns in training.
We then cut to Earth, where Will Smith’s character, John Stewart, a former marine now turned architect, is living a quiet life in Detroit. He is shown sketching blueprints and reflecting on his past life in the military. The calm is interrupted when a mysterious, glowing green ring appears before him, choosing him as the next Green Lantern. The ring’s power envelops him, and we see John Stewart experience an overwhelming surge of energy. As he struggles to comprehend what is happening, a flash of emerald light transports him to Oa.
On Oa, John is introduced to the Green Lantern Corps. He meets Kilowog (voiced by Dave Bautista) and the veteran Hal Jordan (played by Ryan Reynolds in a cameo), who begins training him in the ways of the Corps. John’s reluctance is evident—he questions why he was chosen, despite Hal’s insistence that the ring never makes mistakes. In a tense moment, John expresses his doubts: “I’m no hero, and I’m definitely not ready to protect the universe.” Hal responds with a serious tone: “The universe doesn’t wait for you to be ready.”
The trailer quickly escalates into an action-packed montage. Scenes of intergalactic battles flash by as the Green Lantern Corps fights against an overwhelming new threat—an ancient entity known as Parallax, a being of pure fear that has returned to seek vengeance on the Guardians. Parallax’s shadowy tendrils spread across planets, corrupting life and destroying everything in their path. John is thrust into this cosmic war, despite his inexperience, forced to defend Earth and the galaxy at large.
We get glimpses of John Stewart using the ring’s power to form massive constructs—jets, shields, and weapons—while battling hordes of Parallax’s fear-corrupted soldiers. Explosions light up the galaxy as John’s abilities are pushed to the limit.
The final moments of the trailer show John, floating above Earth, looking down at the planet he swore to protect. He clenches his fist, the Green Lantern ring glowing brightly, as he says the iconic oath: “In brightest day, in blackest night… no evil shall escape my sight.”
The trailer ends with the title Green Lantern and the tagline: “The universe’s greatest protector has arrived.”
