Final trailer and release
Amazon MGM Studios has released the official final trailer for the live-action adventure film Masters of the Universe, which is set to open in theaters on June 5, 2026.
“Masters of the Universe opens in theaters on June 5, 2026.”
The story premise in the trailer has Prince Adam (Nicholas Galitzine) separated for 15 years before the Sword of Power leads him back to Eternia, where he discovers his home shattered under the fiendish rule of Skeletor (Jared Leto).
To save his family and his world, Adam must join forces with his closest allies, Teela (Camila Mendes) and Duncan/Man-At-Arms (Idris Elba), and embrace his true destiny as He-Man.
The cast also includes Alison Brie as Evil-Lyn and Kristen Wiig as the voice of “Roboto,” with Jared Leto and Idris Elba among the credited stars in IGN’s trailer coverage.
Knight, Galitzine, and body
Director Travis Knight is credited with bringing the franchise back to the big screen, and Out Magazine highlights how the final trailer keeps Nicholas Galitzine’s physical transformation front and center.
Out Magazine reports that Galitzine’s press tour conversation focused on his “boulder shoulders,” “giant biceps,” “rippling pectorals,” and “six-pack abs,” quoting Knight’s Variety interview joke: "That means boulder shoulders. That means giant biceps. That means rippling pectorals and six-pack abs."
Out Magazine also quotes Galitzine describing how, after filming wrapped, he slowed down and ate “macaroni and cheese,” adding, "It was sickening."
The same final-trailer framing appears in Ars Technica’s recap of the official premise, which again centers on Adam returning to Eternia and joining Teela and Duncan/Man-At-Arms to confront Skeletor.
Eternia cast and universe
Beyond the core trio of Adam, Teela, and Duncan/Man-At-Arms, the film’s ensemble is expanded across outlets with additional characters tied to Eternia and its lore.
“"Masters of the Universe" is set to open in cinemas on June 5th.”
Dark Horizons lists a broad cast including Alison Brie as Evil-Lyn, Camila Mendes as Teela, Idris Elba as Man at Arms, Morena Baccarin as the Sorceress, and Jared Leto as Skeletor, while also naming Kristen Wiig as Roboto and Jóhannes Haukur Jóhannesson as Fisto.
JoBlo adds that the film is produced by Todd Black, Jason Blumenthal, Robbie Brenner, Steve Tisch, and DeVon Franklin, and it says the U.S. theatrical release is June 5, 2026 with worldwide release the same month by Sony Pictures International Releasing.
Ars Technica further specifies roles such as Kristen Wiig as Roboto and Sasheer Zamata as Suzie, while also tying the project to the franchise’s wider ecosystem by noting it is a reboot of the He-Man and Masters of the Universe series and its spinoff She-Ra: Princess of Powers.
