Nathan Fillion’s 8-Part HBO Series Sets the Stage for DC’s 2027 Event

A Different Side of Guy Gardner
In Superman, Guy Gardner appeared in costume and used his Power Ring to create elaborate constructs. Lanterns takes a different approach: it is a grounded crime drama centered on a murder mystery on Earth, with little cosmic spectacle.
The series preserves Guy’s immature insults and bravado while giving him more edge. Fillion’s performance also reveals the insecurity beneath that confidence, making Guy more than comic relief.
The Finale Changes Their Roles
Lanterns is largely separate from the wider DC Universe, without cameos from Superman or Supergirl or a post-credits scene setting up Clayface. Its finale, however, points toward Superman sequel Man of Tomorrow.
Guy remains Earth’s official Green Lantern, answerable to the Guardians of the Universe and tasked with intergalactic threats. John Stewart becomes a renegade Green Lantern, protecting Earth with his own Lantern, Power Ring and version of the traditional oath.
A 2027 Team-Up
John and Guy are both confirmed for Man of Tomorrow, scheduled for theaters on July 9, 2027. The film brings Superman together with former enemy Lex Luthor to face Brainiac, played by Lars Eidinger.
The ensemble also includes Mister Terrific, Hawkgirl and Jimmy Olsen, while Adria Arjona has an undisclosed role. Xolo Maridueña’s Blue Beetle and Aaron Pierre’s Green Lantern are also joining the wider DCU cast.
What Comes After Lanterns
The two Green Lanterns’ contrasting duties could lead to conflict when they appear together in the sequel. Their partnership may also show how the Guardians respond to John’s independent approach.
A second season of Lanterns has not been officially confirmed, though the article describes it as likely after the first season’s success. The series could continue exploring John’s new path after the film’s setup.
Key points
- Lanterns gives Nathan Fillion’s Guy Gardner a grounded story and reveals insecurity beneath his bravado.

- Both Green Lanterns are confirmed for Man of Tomorrow, due in theaters July 9, 2027.
