Nicholas Galitzine Reveals His 'Sword of Power' in Shirtless 'He-Man' Photo

"Red, White & Royal Blue" actor Nicholas Galitzine is set to star as He-Man in the upcoming live action "Masters of the Universe" feature - and the bulked-up thesp teased his look in an Instagram post, showing off his armor-laden chest along with his impressively massive "Sword of Power."

Galitzine, who has been adding muscle for the role, captioned the pic with, "After several months of intense training, I'm thrilled to share that we're officially in production on #MastersOfTheUniverse."

"I can't wait for you to see," Galitzine added. "More to come, but until then, here's a sneak peek at the Sword of Power."

The post finished up with a rousing, "By the power of Grayskull!"

Fans expressed their enthusiasm for the project - and for Galitzine's impressive physique.

"👏Wow your parts keep getting bigger & bigger!!!" one person responded, while another declared, "Our babygirl turned into a beast 😱💪."

Joked a third: "i'm seated. the theater employees are scared and asking me to leave because 'production just started,' but i'm simply too seated."

The image soon ventured far and wide.

"A fan account for the Masters of the Universe cartoon shared the photo, noting Eternia's 'in good hands' by the looks of Nicholas' ripped transformation," E! Online relayed.

"The forthcoming film - which will release in June 2026 - is based on the Mattel's He-Man line that launched in 1982, and later, his popular rise in DC Comics," E! Online added.

Galitzine's share, even dominated by the massive sword, is the most revealing look yet at the "Mary & George" heartthrob's transformed body, though images he has posted to his Insta over the last year have shown him noticeably gaining mass. He's also gone blond for the part.

An image shared to X earlier this month also gave fans a hint of how much muscle Galitzine has packed onto his frame, though the photo - which shows the actor posing in an oversized T-shirt with trainer Hafthor Bjornsson and co-star Camila Mendes - only suggested how physically powerful the actor has become.

The cast for "Masters of the Universe" also includes Jared Leto as Skeletor, Idris Elba as Man-At-Arms, James Purefoy as King Randor, Alison Brie as Evil-Lyn, and Morena Baccarin as The Sorceress.
