You've seen the thumbnail. It's usually a high-contrast shot of David Corenswet’s Superman hovering in space, his eyes glowing a soft emerald green, while a ringed hand reaches out from the shadows. Maybe the title says "First Look" or "Official Teaser." You click it. You’re hyped. Then, about thirty seconds into the video, you realize something is off. The lighting looks like a video game. The voiceover sounds like a robot trying to imitate Henry Cavill. The "Green Lantern Superman trailer" you just found is, quite frankly, a total fake.
It’s frustrating.
We are currently in a weird limbo for the DC Universe (DCU). James Gunn is rebuilding the whole house from the ground up. Because fans are starving for any scrap of footage from the upcoming Superman (2025) or the Lanterns HBO series, the internet has become a minefield of "concept trailers." These aren't just fan edits anymore; they are sophisticated AI-generated deepfakes designed to farm clicks.
Honestly, the real story of how Green Lantern and Superman will eventually meet on screen is way more interesting than a two-minute montage of stolen Interstellar clips and CGI lanterns.
The state of the DCU and that elusive Green Lantern Superman trailer
Let’s get the facts straight. As of right now, there is no official trailer, teaser, or even a "sizzle reel" that features both Superman and a Green Lantern together.
James Gunn’s Superman wrapped filming in mid-2024. We’ve seen the suit. We know Nathan Fillion is playing Guy Gardner (one of the Earth-based Green Lanterns). But if you’re looking for a joint Green Lantern Superman trailer, you’re looking for something that hasn't been cut yet. The marketing machine for the new DCU is barely starting to turn its gears.
Why is everyone searching for this specifically? It’s likely because of the cast list. Unlike previous versions of Superman movies that kept the Man of Steel isolated in his own bubble, Gunn’s movie is crowded. It’s got Hawkgirl, Mister Terrific, Metamorpho, and—most importantly—Guy Gardner. The proximity of a Green Lantern to the Last Son of Krypton in the very first movie of the new era has sent the hype train into overdrive. People want to see the dynamic. They want to see the green light against the red cape.

Why the "Concept" trailers keep winning
The algorithm loves a vacuum. When there is a high search volume for a term like "Green Lantern Superman trailer" and zero official results, YouTube’s recommendation engine fills that gap with whatever it can find.
Channels like Screen Culture or KH Studio have mastered this. They use "Concept" in the title, which is their legal shield, but the thumbnails are designed to look like official Warner Bros. press releases. They often use footage from Man of Steel, Green Lantern (2011), and even cutscenes from the Injustice video games. If you’ve been fooled, don't feel bad. The AI upscaling on these fan edits is getting eerily good.
But here is the catch: none of that footage reflects the actual aesthetic James Gunn is going for. The new DCU is leaning into a "lived-in" comic book feel. Guy Gardner's bowl cut and tactical vest are a far cry from the glowing CGI bodysuit Ryan Reynolds wore over a decade ago.
When will we actually see a real trailer?
If you want the real deal, you have to look at the production calendar. Warner Bros. Discovery typically drops major trailers about six to eight months before a film's release.
Superman is slated for July 11, 2025.

That means the first real footage—the one that might actually show Nathan Fillion’s Guy Gardner interacting with David Corenswet’s Clark Kent—isn't likely to hit the web until late 2024 or the very beginning of 2025. Super Bowl LIX in February 2025 is a massive candidate for a "Big Game" spot.
The Lanterns series connection
There’s another reason the Green Lantern Superman trailer is such a hot topic. HBO is developing a series titled Lanterns. It’s being described as a True Detective style mystery involving Hal Jordan and John Stewart.
While this show is separate from the Superman movie, they exist in the same continuity. Rumors have been swirling that Hal or John might make a cameo in the movie, or that Superman might appear in the show. This cross-pollination is what the fans are actually hunting for when they type those keywords into Google. They are looking for proof of a connected universe.
Spotting the fakes: A quick checklist
If you see a Green Lantern Superman trailer tomorrow, how do you know if James Gunn actually posted it or if it’s just another fan edit?
- The Channel Source: If it isn't on the official "Warner Bros. Pictures" or "DC" YouTube channels, it’s 99% likely to be fake.
- The Voiceover: Listen to the dialogue. If it sounds like lines from previous movies or a slightly "flat" AI voice, close the tab.
- The "Suit": Look at Superman’s S-shield. The official DCU shield is the yellow and red "Kingdom Come" inspired design with a black background (sometimes seen in set photos). If you see the classic Henry Cavill or Christopher Reeve shield, it’s a fan edit.
- Guy Gardner's Hair: Nathan Fillion is rocking a very specific, very ridiculous red bowl cut for this role. If the Green Lantern in the trailer has a mask and a standard haircut, it's old footage.
The narrative weight of the Green Lantern and Superman duo
In the comics, the relationship between these two is legendary. It’s not just about the powers. It's about the clash of jurisdictions.
Superman is a freelance hero. He does what he thinks is right. Green Lanterns are intergalactic cops. They have a boss (the Guardians of the Universe) and a handbook. When you put a guy like Guy Gardner—who is basically the "jerk" of the Green Lantern Corps—next to a hopeful, "big blue boy scout" Superman, you get instant friction.
That friction is what the fake trailers are trying to capture, but they miss the nuance. They focus on the spectacle of a fight. The real movie will likely focus on the character work. How does Superman feel about a space cop patrolling his backyard? That’s the meat of the story.
What we know for sure about the official footage
Instead of chasing ghosts, here is what is actually confirmed for the upcoming DCU slate that involves these characters:
- David Corenswet is Superman: He’s bigger than he was in The Politician. The suit is thick, textured, and looks a bit like armor.
- Nathan Fillion is Guy Gardner: He’s a Green Lantern, but he’s not the only one. This is key. The existence of Guy implies the existence of the entire Corps.
- The Setting: Metropolis is being built as a retro-futuristic city. It’s bright.
- The Tone: James Gunn has repeatedly said this isn't a "dark and gritty" reboot. It’s a movie about hope.
So, when that first Green Lantern Superman trailer finally drops, expect it to be colorful. Expect it to be a bit funny. Don't expect the moody, desaturated look of the Snyderverse that the fan trailers keep trying to replicate.
How to stay updated without the clickbait
The best way to see the actual trailer the second it goes live isn't through a YouTube search. Follow the creators directly. James Gunn is incredibly active on Threads and Instagram. He often debunks fake news personally.
When a trailer is ready, he usually announces the "drop date" a few days in advance. He’s a fan of the "trailer for a trailer" hype cycle, but he’s also very transparent. If he hasn't posted it, it doesn't exist.
What to do next
Stop rewarding the clickbait farms. Every time a fake "Green Lantern Superman trailer" gets a million views, it incentivizes more people to flood the search results with AI garbage. This makes it harder for actual news—like casting updates for Hal Jordan or official set photos—to reach the top of the page.
If you want to see what the DCU actually looks like right now, look for the official "Superman" set photos that were released by Warner Bros. during the Cleveland shoot. They show Corenswet in the suit, and they give a much better sense of the film’s visual language than any fan edit ever could.
Actionable Steps:
- Bookmark the Official DC YouTube Channel: This is the only place where the real trailer will debut.
- Follow James Gunn on Threads: He is the primary source for all DCU "truth."
- Check the "Official" Tag: On Google News, look for reporting from trades like Variety, The Hollywood Reporter, or Deadline. If they aren't talking about a trailer, there isn't one.
- Report the AI Fakes: If a video is titled "Official Trailer" but is clearly fan-made, use the report feature for "Spam or misleading" to help clean up the search results for other fans.
The wait is annoying, but the payoff of seeing a high-budget, professionally shot interaction between a Green Lantern and Superman will be worth more than a thousand AI-generated concepts. Stay patient. The real DCU is coming.
