Every Actor in ‘Masters of the Universe’ and the Iconic Roles They’re Bringing to Life

The long and winding road to Eternia is finally complete. ‘Masters of the Universe‘ releases theatrically in the U.S. on June 5, 2026, distributed by Amazon MGM Studios, with Nicholas Galitzine starring as Prince Adam and He-Man alongside Jared Leto and Idris Elba, under the direction of Travis Knight. After spending decades in development limbo, the franchise is back with one of the most stacked ensemble casts in recent blockbuster memory.

Backed by a budget estimated between $170 and $200 million, the film is a co-production between Amazon MGM Studios, Mattel Studios, and Escape Artists, with Sony Pictures Releasing handling international distribution. The scale of ambition here is impossible to ignore, and every casting choice tells a story about exactly what kind of movie this intends to be.

Nicholas Galitzine and the He-Man Transformation

The entire project rests on whether audiences buy Nicholas Galitzine as He-Man, and by all accounts, the actor left nothing on the table. The 31-year-old British actor bulked up considerably to play the iconic character, and Galitzine called getting into He-Man shape “the hardest thing I’ve ever done.”

Galitzine began training for the role at least as far back as May 2024, and production ran from February to June 2025, with the actor simultaneously training while filming other projects. The commitment extended well beyond the gym. In an interview, Galitzine told Entertainment Weekly that the physical preparation took a full six months of dedicated work minimum and that it was “really not for the faint of heart.”

The film follows Prince Adam’s story of being separated for fifteen years before the Sword of Power leads him back to Eternia, where he discovers his home shattered under the rule of Skeletor and must embrace his destiny as He-Man, the most powerful man in the universe. It is a classic hero’s journey, and Galitzine’s physical reinvention gives it genuine visual weight.

Jared Leto as Skeletor and the Villain Ensemble

Jared Leto plays Skeletor, with Alison Brie joining as Evil-Lyn, Skeletor’s second-in-command. The villain side of the roster is arguably where the film’s most intriguing casting decisions live.

Director Travis Knight himself described Skeletor as a psychopathic manchild, a man who while genuinely powerful and threatening also embodies the wrong idea of masculinity and is deeply dependent on his worldview. That framing suggests a Skeletor with genuine menace rather than camp, which is a significant creative swing.

Sam C. Wilson fills the role of Trap Jaw, Hafþór Júlíus Björnsson plays Goat Man, and Kojo Attah takes on the role of Tri-Klops. The sheer number of named villain characters suggests the film is building a proper army for Skeletor rather than leaving him isolated as a solo antagonist.

Reports have emerged that Leto was not entirely happy with the finished film, having missed CinemaCon and the world premiere in Los Angeles, with Amazon said to be downplaying his involvement despite him being among the biggest names in the cast. Whether that behind-the-scenes friction affects the performance onscreen remains a question only the film itself can answer.

The Heroes of Eternia and the Supporting Cast

Idris Elba portrays Duncan, otherwise known as Man-At-Arms, and Camila Mendes plays Teela in the film. Both characters serve as Prince Adam’s closest allies in his mission to reclaim Eternia, and the pairing of Elba and Mendes with Galitzine gives the heroic trio real marquee firepower.

Camila Mendes, who previously starred as Veronica Lodge in the CW’s ‘Riverdale’, takes on the action-packed role of Teela, the captain of the guards and Man-At-Arms’ adoptive daughter. Meanwhile, Charlotte Riley of ‘Peaky Blinders’ and ‘The Peripheral’ portrays Queen Marlena, a human from Earth who became an intergalactic pilot before becoming stranded on Eternia and eventually becoming the planet’s queen.

James Purefoy plays King Randor, Morena Baccarin appears as the Enchantress, the magically inclined protector of Castle Grayskull, and Jóhannes Haukur Jóhannesson takes the role of Malcolm, also known as Fisto. The casting of these supporting roles anchors the world of Eternia with performers who bring serious dramatic credibility.

Kristen Wiig, Dolph Lundgren, and the Wild Cards

Perhaps no casting choice in ‘Masters of the Universe’ has generated more curiosity than Kristen Wiig’s. Wiig voices Roboto, a mechanical warrior built by Man-At-Arms, described as having a transparent metal body allowing one to see its inner workings and an arm with interchangeable attachments including a claw, laser gun, and axe.

The character has traditionally been voiced by a male actor, making Wiig’s casting a deliberate subversion of expectation. It is the kind of choice that signals the filmmakers are not simply replicating the source material beat by beat but are willing to play with it.

The full cast also includes Hafþór Júlíus Björnsson, Sasheer Zamata, Jon Xue Zhang, and Dolph Lundgren, who starred in the original 1987 live-action film. Lundgren’s inclusion is certain to land as a major crowd-pleasing moment for fans who grew up with the franchise, though the specifics of his role are being kept quiet ahead of release.

What the Critics Are Already Saying

Early reviews have arrived with cautious optimism. One critic described the film as succeeding by doing something refreshingly straightforward, telling a rousing fantasy adventure with conviction, humor, and heart, freed from the burden of contemporary relevance.

According to Deadline, the film carries a PG-13 rating and runs two hours and twelve minutes. That runtime suggests a full-scale adventure rather than a lean, stripped-down origin story, which lines up with what the production’s reported scale promises.

Director Travis Knight, whose previous credits include ‘Kubo and the Two Strings’ and the widely praised ‘Bumblebee’, has built the film on a screenplay co-written by David Callaham, whose credits include ‘Shang-Chi’ and ‘Spider-Man: Across the Spider-Verse’. That creative pedigree gives real reason to believe this is a franchise reboot with genuine craft behind it, not just a nostalgia extraction exercise.

With opening day here, the conversation around who landed the definitive version of these characters is only just beginning, and there is no better time to weigh in on whether this cast feels like the right team to carry the power of Grayskull into a new era.
