Nathan Fillion Clarifies Guy Gardner & John Stewart's Next DC Reunion After Lanterns Finale

A reunion after Lanterns

On the Once We Were Spacemen podcast, Fillion said viewers would see his Guy Gardner alongside Pierre’s John Stewart again soon. The actors have filmed scenes for James Gunn’s Man of Tomorrow.

Fillion said he and Pierre had already built a rapport while working on Lanterns. He also praised the actors he worked with on the series, including Pierre and Kyle Chandler, who plays Hal Jordan.

Their duties split

In Lanterns, the Guardians of the Universe chose Guy to replace Hal after Hal was imprisoned. John had originally been considered for the role, setting up a rivalry between the two characters.

The season finale ended after a tense dispute over John’s unsanctioned ring and battery. Guy stayed the official Green Lantern for Space Sector 2814, while John took over duties on Earth.

What comes next for DC

Man of Tomorrow is written and directed by Gunn, and follows Superman and Lex Luthor as they work together against a larger threat. The film is set for release on July 9, 2027.

David Corenswet, Nicholas Hoult, Rachel Brosnahan, Milly Alcock, Isabela Merced, Edi Gathegi, Fillion, Skyler Gisondo and Frank Grillo are among the returning cast. New cast members include Pierre as John Stewart, Xolo Maridueña as Blue Beetle, Lars Eidinger as Brainiac and Adria Arjona in an undisclosed role.

Gunn and Peter Safran have stepped down as DC Studios co-CEOs, and the franchise’s future is uncertain. A report says the leadership change could dismantle Gunn’s long-term plans, though projects already filmed or in production are expected to proceed; Lanterns season 2 has not been renewed.
