Concept artist Joe Studzinski just revealed Alan Scott designs from the scrapped Green Lantern: Emerald Knights

Concept artist Joe Studzinski posted Alan Scott Green Lantern designs from the cancelled HBO Max series 'Emerald Knights' on Instagram, preserving a locked visual mythology — including the Starheart, a train lantern, and an 1800s lampmaker origin — that was erased when James Gunn's DC Studios reboot replaced the show with 'Lanterns.'

In 2019, Greg Berlanti began developing an ambitious Green Lantern series for HBO Max, initially described as the platform's most expensive production. The project was written by Marc Guggenheim and Seth Grahame-Smith, and was originally conceived as a multi-decade, space-spanning ensemble saga tentatively titled "Emerald Knights."

About this episode

When concept artist Joe Studzinski posted Alan Scott designs from the cancelled HBO Max series Green Lantern: Emerald Knights, it looked like a portfolio move. The episode argues it's something more specific than that — an acknowledgment that a finished creative work existed, because the studio that killed it cannot make that acknowledgment itself. The scale of what got buried is worth sitting with. Greg Berlanti pitched the show in 2019 as HBO Max's most expensive production. Showrunner Seth Grahame-Smith finished all eight scripts before leaving in October 2022. Jeremy Irvine was locked as Alan Scott, Finn Wittrock as Guy Gardner. Co-creator Marc Guggenheim has since revealed the title (Emerald Knights), the main villains (the Manhunters), and an entirely original character named Bree Jarta — a half-alien Green Lantern with no comic counterpart, built from scratch for this show. The episode traces how two separate hits finished it: Grahame-Smith's exit destabilized the creative spine, and then Gunn and Safran's clean-slate mandate made survival structurally impossible. What makes the loss distinct is that Alan Scott's mystical mythology — the Starheart, the train lantern, the 1840s lampmaker origin — has no equivalent in Gunn's Lanterns, which is Hal Jordan's world. It's not a delay. It's a permanent gap. And Bree Jarta, who exists only in those eight scripts, has nowhere left to go.

Frequently asked

What was the cancelled HBO Max Green Lantern series?

'Emerald Knights' was a cancelled HBO Max Green Lantern series developed by Greg Berlanti and co-creator Marc Guggenheim. It had eight completed scripts by Seth Grahame-Smith, Jeremy Irvine cast as Alan Scott, Finn Wittrock as Guy Gardner, and the Manhunters as main villains before DC Studios' reboot erased it.

Who is Bree Jarta and what happened to her?

Bree Jarta is an original half-alien Green Lantern character created specifically for the cancelled HBO Max series 'Emerald Knights.' She has no comic book counterpart, meaning she cannot be revived in James Gunn's DCU. She exists only in Marc Guggenheim's Substack posts and the eight unproduced scripts.

Why did the HBO Max Green Lantern show get cancelled?

The HBO Max Green Lantern series 'Emerald Knights' was cancelled in two blows: showrunner Seth Grahame-Smith departed in October 2022 after finishing all eight scripts, prompting a retool toward John Stewart; then James Gunn and Peter Safran's clean-slate DC Studios mandate structurally eliminated it in favor of the separate series 'Lanterns.'

What did Jeremy Irvine say about the cancelled Green Lantern show?

Jeremy Irvine, who was cast as Alan Scott in the cancelled HBO Max Green Lantern series, told The Direct the scripts were 'great' and that he is 'gutted' the show was cancelled. Irvine cited NDAs as the reason he could not say more, indicating he remains legally restricted from discussing full details.

How is James Gunn's Lanterns different from the cancelled Emerald Knights?

James Gunn's 'Lanterns' centers on Hal Jordan within a science-fiction ring-and-corps mythology, while the cancelled 'Emerald Knights' focused on Alan Scott's mystical Starheart origin rooted in the 1940s and connected to an 1800s lampmaker named Billings. The two shows draw on entirely different Green Lantern traditions from DC Comics.

Cole Bryant: Hey — quick question before we do anything. If your studio buries eight finished episodes and a locked visual mythology, what's the one thing you can still do?

Zara Reyes: Post it yourself.

Cole Bryant: Post it yourself. Which is exactly what Joe Studzinski just did — Alan Scott concept art, the Starheart, a train lantern, a whole origin involving an 1800s lampmaker named Billings — all of it, on Instagram, from the cancelled HBO Max Green Lantern series. And then Marc Guggenheim goes to Substack and drops Bree Jarta, Guy Gardner, and reveals the title was 'Emerald Knights' with the Manhunters as the main villains.

Zara Reyes: Hold on — Bree Jarta is the original character, right? Never-been-on-screen, created specifically for this series?

Cole Bryant: Half-alien Green Lantern, built from scratch for the show. Never made it anywhere near a camera. And now she's living on Guggenheim's newsletter.

Zara Reyes: No but that's the thing — Jeremy Irvine is out here in The Direct saying the scripts were 'great,' that he's 'gutted,' and NDAs are the reason he can't say more. So the cast is legally muzzled and the creative team is just... posting.

Cole Bryant: And that gap is the whole story. Because Studzinski going public with that Alan Scott art isn't him processing loss — it's him telling the next DC exec or Netflix exec or whoever, 'I built a complete visual language for a flagship superhero, here's the proof.' It's a portfolio move. Full stop.

Zara Reyes: Lowkey the only power move left when a reboot takes everything else.

Cole Bryant: But wait — portfolio move only works if there's actually a portfolio worth showing. And I keep saying that without, like, sitting with how finished this thing actually was.

Zara Reyes: Thank you. That's the part I need us to land on.

Cole Bryant: Because Berlanti pitched this in 2019 as HBO Max's most expensive production. That's the number. Most. Expensive. And Seth Grahame-Smith — dude finished eight full scripts. All eight. Then left in October 2022. So the scripts exist. They're sitting in a drawer at Warner Bros. right now.

Zara Reyes: No but that's — that changes the whole frame. This wasn't a mood board. This was titled. 'Emerald Knights.' Jeremy Irvine locked as Alan Scott, Finn Wittrock locked as Guy Gardner. Bree Jarta — a completely original half-alien character with zero comic counterpart — built from scratch. That's not development, that's a buried show.

Cole Bryant: A buried show with — wait, they also dropped the episode count, right? Started at ten, got cut to eight before it even —

Zara Reyes: Before it got retooled, yeah. And then Gunn and Safran come in and it's just — gone. So when Studzinski posts that Alan Scott art, he's not showing a sketch. He's showing proof that a specific visual mythology was locked. The Starheart. The train lantern. The 1940s aesthetic. That's not vibes, that's a bible.

Cole Bryant: So the portfolio-move framing — I mean, it's still true, but it's almost — no, actually it undersells it. Because Bree Jarta dies permanently. She has no comic to fall back on. Nobody's reviving her in the Gunn universe.

Zara Reyes: That's the part that's actually sad. Like, genuinely.

Cole Bryant: And Irvine is out there saying the scripts were great, he's gutted, NDAs everywhere — bro, that's not an actor doing promo. That's someone mourning a real thing that got politically killed. The creative quality was irrelevant. Gunn needed a clean slate, so clean slate.

Zara Reyes: But 'politically killed' is doing a lot of work there. Because it wasn't one thing — it was two separate hits, back to back, and either one alone might not have finished it.

Cole Bryant: Right — and that's actually where the hot take earns something. Because Grahame-Smith walks out in October 2022 — after finishing all eight scripts — and Warner Bros. doesn't cancel it, they retool it. Pivot to John Stewart. Berlanti stays on but he's basically the last original crew member standing at that point.

Zara Reyes: Greg Berlanti, sole survivor.

Cole Bryant: Sole survivor! And the show is — wait, no, it's already wounded at that point, right? Like, the Grahame-Smith exit isn't a clean handoff, it's a crisis. Scripts exist but the creative spine just left the building. And then — before they can even stabilize — Gunn and Safran form DC Studios and it's a clean-slate mandate. Suddenly the retooled version doesn't just get cancelled, it gets structurally erased. It was never going to survive that second hit.

Zara Reyes: No but that's the part that's genuinely brutal. Those eight Grahame-Smith scripts — they didn't fail a writers room vote. They cleared development. Cast locked. Episode order set — well, reduced from ten to eight, but set. The work was done.

Cole Bryant: Done and then Gunn announces Lanterns — Chapter One, Gods and Monsters — and it's like, that's your replacement. Different show, different universe, different rules. The Berlanti version doesn't just lose funding, it loses the right to exist.

Zara Reyes: Which is why Studzinski posting that Alan Scott art is — lowkey, it's the only counter-move available. And there's a part of this we haven't even touched yet that makes it worse.

Cole Bryant: What part?

Zara Reyes: That Alan Scott's entire mythology — the Starheart, the 1940s origin, the train lantern — none of it exists anywhere in Gunn's DCU. That's not a delay. That's a permanent gap. We'll get there.

Cole Bryant: Wait — permanent gap is the right word, actually. Because Gunn's Lanterns isn't a different take on the same mythology. It's a structurally different show. Ring-and-corps, Hal Jordan energy, science-fiction infrastructure. Alan Scott's whole thing is mystical — the Starheart, a 1940s origin, a train lantern connected to an 1800s lampmaker named Billings. That's not the same source material. Those are two completely different traditions wearing the same name.

Zara Reyes: They're not even cousins. Alan Scott predates the ring mythology entirely.

Cole Bryant: Right — and so when Studzinski posts that art, he's not just preserving a cancelled show. He's preserving the only version of Alan Scott that was ever going to exist on screen. Because Gunn's not touching that corner of the mythology. Lanterns is Hal Jordan's world.

Zara Reyes: And Bree Jarta — no, this is the part that actually gets me. She doesn't exist in any comic. She only ever existed in those eight scripts and Guggenheim's Substack images. Gunn's DCU can't revive her because she was never in the source material to begin with.

Cole Bryant: She's just gone.

Zara Reyes: Permanently. So the calibrated take — strip the fan grief, strip the portfolio framing — what Studzinski actually posted is proof that something with no replacement got deleted. That's its own category. It's not a delay, it's not a rights issue, it's not 'maybe someday.' The Starheart mythology, Bree Jarta, the Billings lampmaker origin — none of that has anywhere to go in the current DC pipeline.

Cole Bryant: And Gunn and Safran's whole reboot logic, I mean — it basically requires treating the Berlanti version as if it never existed. That's not a bug, that's the mandate. Clean slate means you can't acknowledge what got erased.

Zara Reyes: Which is exactly why Studzinski posting it is the counter-move. The Instagram post is the acknowledgment DC Studios structurally cannot make.

Cole Bryant: So it's not a portfolio move and it's not just grief — it's a record. Like, someone has to say this specific thing existed and it was finished and it's gone. And now it's on Instagram forever.

Zara Reyes: My detail is Bree Jarta. Half-alien, built from scratch, no comic, no Gunn pipeline, just — Guggenheim's Substack and then the void.

Cole Bryant: Mine is the train lantern. That's — I mean, Studzinski designed a whole visual mythology around a train lantern connected to an 1800s lampmaker and it's just sitting on Instagram right now doing more preservation work than any museum.

Zara Reyes: Knowing DC Studios? They'll reboot the reboot, hire someone new, and that train lantern concept will still just be there. On Instagram. Doing more work than any show that actually aired.

Cole Bryant: Okay wait — that's actually it. That's the whole thing. Studzinski wins by posting.

Zara Reyes: He already won. Cheers to the train lantern.
