Marc Guggenheim has shared concept art and story details from an earlier, canceled Green Lantern television project pitched under the title Emerald Knights. The reported plan paired Alan Scott’s 1941 story with Guy Gardner’s 1984 story, brought the Manhunters in as the main villains, and leaned into cosmic adventure. It shares some ingredients with HBO’s later Lanterns, but the two are distinct projects—not a continuation and its predecessor.
What was the canceled Green Lantern show supposed to be?
Guggenheim, the Arrow co-creator, shared concept art on Substack from the earlier project. TVLine quoted him describing its premise: “Our original took place in two time periods and had the Manhunters as the primary villains and my original title pitch was ‘Emerald Knights.’” TVLine

Reports place the story in 1941 and 1984, with Alan Scott and Guy Gardner at its center. Jeremy Irvine was attached to play Scott, while Finn Wittrock was attached to play Gardner, according to GamesRadar+. These were reported attachments for the canceled project, not roles in Lanterns.
What did the concept art reportedly show?
TVLine described art depicting Lanterns fighting aliens with green construct weapons, alongside an early costume design for Gardner. GamesRadar+ also reported a space battle and costume concepts for Gardner and Bree Jarta. The Gardner design was reportedly expected to move closer to his Justice League International look.

Bree Jarta’s place in the story
GamesRadar+ reported that Bree Jarta was a new half-alien, half-human Lantern focused on the 1980s portion of the story. It also said one Lantern design drew on Janelle Monáe’s likeness. That does not mean Monáe was cast: the report said the production had not found an actor for Bree.
How is Emerald Knights similar to HBO’s Lanterns?
| Element | Earlier project, Emerald Knights | Later series, Lanterns |
|---|---|---|
| Setting and scale | Reported as a cosmic adventure with Lanterns fighting aliens. TVLine | Described in the reporting as an Earth-focused story. TVLine |
| Time structure | Two periods: 1941 and 1984. GamesRadar+ | Also reported as using multiple periods. GamesRadar+ |
| Featured Lanterns | Alan Scott and Guy Gardner were central figures; Bree Jarta was also planned for the 1980s story. GamesRadar+ | Reported focus on Hal Jordan and John Stewart. TVLine |
| Antagonists | The Manhunters were to be the primary villains. TVLine | The Manhunters are also noted as an element shared by the projects. GamesRadar+ |
The overlap is real, but it supports a comparison of concepts—not a claim that Lanterns continues, remakes, or directly replaces Emerald Knights. The reported cast, central characters, and scale differ.

Why was the earlier project canceled?
Coverage connects the project’s redevelopment to the broader DC Studios transition and the arrival of James Gunn and Peter Safran. The cited reports do not establish a single official explanation from HBO or DC for the cancellation, so a definitive cause cannot be assigned from them. TVLine and GamesRadar+
Even the episode order is unsettled in accessible coverage: GamesRadar+ reported that an initial 10-episode pickup was reduced to eight, while tbreak cautioned that accounts differed. GamesRadar+ and tbreak
