The Physical Transformation: How Galitzine Became the Most Powerful Man in the Universe

The role of He-Man, the hulked-out hero of Eternia, demands a physique that matches the character’s legendary strength. Nicholas Galitzine’s commitment to the role has been evident through his intense physical metamorphosis, which has become a major talking point among fans.

The Intense Training Regimen

Galitzine has openly discussed the demanding nature of his training, describing the physical transformation as "intense." Unlike his previous roles, which often required a more slender, romantic lead appearance, playing He-Man required him to gain significant muscle mass to accurately portray Prince Adam's powerful alter-ego. The actor shared behind-the-scenes glimpses on social media, showing off his chiseled physique and massive muscle gains, which quickly went viral. This preparation ensures that when Prince Adam raises the Power Sword and declares, "I have the power!", the visual transformation will be credible and impactful for audiences.

From Prince Henry to Prince Adam

Galitzine's career has been characterized by playing various forms of royalty—from Prince Robert in *Cinderella* to Prince Henry in *Red, White & Royal Blue*. The transition to Prince Adam, however, is his most physically challenging role yet. Fans are eager to see how director Travis Knight handles the dual nature of the character: the sensitive, often underestimated Prince Adam, and the mighty, heroic He-Man. Galitzine’s acting background, combined with his new action-ready physique, suggests a performance that will capture both the heart and the sheer power of the beloved 80s icon. The actor’s dedication to mastering the superhero physique is a clear signal that the production is taking the source material seriously, aiming to deliver a faithful yet modern blockbuster for both long-time fans of the original cartoon and a new generation. The anticipation for the first official look at Galitzine in the full He-Man costume continues to build ahead of the 2026 release.
