Lanterns Teaser Unveils Dual Timelines and Nathan Fillion’s Guy Gardner Appearance

The HBO Max series Lanterns, part of the DC Universe slate, released a teaser in March that feels more like a detective drama than a typical hero show. The trailer emphasizes rain‑slick streets, forensic detail and a small‑town sheriff, echoing the mood of series such as *True Detective*.

Two timelines anchor the story. The first follows a 2016 murder investigation in rural Nebraska, where local law enforcement confronts a crime that quickly draws the attention of intergalactic authorities. The second jumps to 2026, placing the same investigation within a broader, space‑faring conflict. Both strands converge on new recruit John Stewart Jr., played by Aaron Pierre, and veteran Lantern Hal Jordan, portrayed by Kyle Chandler.

Chandler’s Jordan is a former test pilot on the brink of retirement from the Green Lantern Corps, now training Stewart to take his place. The teaser also confirms the return of Nathan Fillion as Guy Gardner, the brash Green Lantern known for his outspoken personality. Fillion appears briefly, offering a nod to longtime fans while hinting at his role in the unfolding mystery.

Supporting characters include Kelly MacDonald as Sheriff Kerry, Jason Ritter as her husband Billy, and Garret Dillahunt as Billy’s father‑in‑law William. Poorna Jagannathan plays Zoe, Ulrich Thomsen is cast as the rogue former Lantern Sinestro, and Paul Ben‑Victor portrays an alien named Antaan.

The shift toward a darker, procedural tone suggests Lanterns will blend crime‑solving with classic superhero elements, aiming to attract viewers who prefer grounded storytelling. By anchoring the plot in a real‑world murder case, the series may explore how intergalactic powers intersect with ordinary law enforcement.

What to watch next: how the dual timelines will intersect and whether Guy Gardner’s cameo signals a larger role for the character in the series’ 2026 arc.
