Henry Cavill reportedly to play King Alfur in Amazon’s live-action Voltron reboot

MovieWeb reported on Jan. 28, 2026 that Henry Cavill is reportedly set to play King Alfur—the legendary warrior and former ruler of Altea—in Amazon MGM Studios’ live-action Voltron reboot, a claim the outlet said it has reached out to confirm and attributed to FeatureFirst. The same report says Sterling K.

Brown is being eyed as Zarkon, the film’s primary antagonist and Alfur’s nemesis. Other names attached in the rumors include Daniel Quinn-Toye as the lead teen who finds one of the five Robot Lions, plus Rita Ora, John Harlan Kim, Alba Baptista, Samson Kayo, Tharanya Tharan, Laura Gordon, Tim Griffin and Nathan Jones.

MovieWeb’s article says the movie is expected to adapt the best-known Voltron series, Defender of the Universe—the mid-1980s run that totaled 124 episodes—and outlines a rumored synopsis in which five teens must learn to pilot robotic lions and unite as Voltron to fight an intergalactic war.

A newly reported synopsis describes a grieving Earth teen who discovers his mother was a legendary Voltron pilot from Altea, and who must take up her lion and reunite Team Voltron after the tyrant Zarkon breaks free and attacks Altea. The report frames these details as rumors rather than confirmed plot points.
