Masters of the Universe: Release date, cast and latest news

Fans have been waiting a long time for a new Masters of the Universe live-action movie – with development on the project having begun all the way back in 2007.

But now, nearly two decades on from then and almost four decades on from the previous film, it's finally on the way – and there's not long to wait at all until we'll get to see Nicholas Galitzine stepping into the role of Prince Adam Glenn/He-Man.

A new trailer for the film was released in January 2026, giving fans a taste of what's to come after some footage had first been glimpsed at CinemaCon last April, and it certainly looks like an action-packed adventure is in store.

In an interview with W Magazine back in January 2025, Galitzine opened up about the intense preparation he underwent ahead of filming. "No pressure, I just have to embody the strongest man in the universe," he joked.

He continued: "There’s been a lot of eating and weightlifting, a lot of stunts. I’m eating about 4,000 calories a day, but the amount of physical work I’m doing, you end up hungry at the end of the day, which is quite surprising. This is the fun part."

Meanwhile, when production wrapped in June, he wrote on Instagram that it had "been the role of a lifetime and I put everything into it", adding that "I am so proud of the movie we’ve made".

Joining Galitzine in the film's cast is Riverdale’s Camila Mendes as Teela, Prince Adam’s Royal Guard Captain and potential love interest, while GLOW star Alison Brie has joined the cast as Evil-Lyn, one of the film's key villains.

Mattel kicked off the Masters of the Universe franchise with a line of action figures that debuted in 1982, with the animated series He-Man and the Masters of the Universe beginning in 1983 before a live-action Masters of the Universe film was released in 1987. More recently, He-Man popped up in a 2021 animated series on Netflix.

So, when can we expect the new film? Read on for everything we know so far.

Masters of the Universe movie plot

The film is based on the 1980s cartoon series, which centres on Prince Adam of Eternia who, thanks to a magic sword, transforms into the powerful He-Man.

Imbued with superhuman strength, he’s tasked with defending his home planet from the villainous sorcerer Skeletor and his armies.

The film’s official synopsis reads: "Ten-year-old Prince Adam crashed to Earth in a spaceship and was separated from his magical Power Sword, the only link to his home on Eternia.

"After tracking it down almost two decades later, Prince Adam is whisked back across space to defend his home planet against the evil forces of Skeletor.

"But to defeat such a powerful villain, Prince Adam will first need to uncover the mysteries of his past and become He-Man: the most powerful man."

Is there a trailer for Masters of the Universe?
