“’Masters of the Universe’ has inspired generations to discover their inner power,” said Nancy Molenda, Mattel’s vice president of global corporate events and philanthropy. “Through this campaign, we’re extending that legacy to children who need it most — working with Amazon MGM Studios and Save the Children to provide the confidence, resources and support they need to shape their futures.”

The campaign hopes to transform the idea that “You Have the Power!” into a global movement, mobilizing fans to help children around the world have a healthy start in life, the opportunity to learn and protection from harm.

“Amazon MGM Studios is honored to support this campaign with Mattel and Save the Children, bringing the ethos of Masters of the Universe beyond the screen to help create real-world impact,” Amazon MGM Studios head of film marketing Stephen Bruno said. “It’s a powerful way to connect fandom with purpose and show that heroism can make a difference in communities everywhere.”

From now through and beyond the movie’s global release date of June 5, retail activations supporting children, immersive experiential moments, community screenings with local organizations and #YouHaveThePower fan content will enhance the campaign.

The Masters of the Universe campaign is part of Mattel’s Play It Forward initiative, which harnesses Mattel’s brands, partners and fans to create meaningful impact for children around the world. Through Play It Forward, Mattel has supported kids in underserved communities, rural areas and regions impacted by crisis and disaster, helping ensure they have access to the resources and opportunities they need to thrive.

Mattel has partnered with Save the Children for more than 20 years.

“The long-standing partnership we’ve built with Mattel around our shared commitment to help children learn, play and thrive has lasted for 20 years,” said Save the Children U.S.’s chief marketing and growth officer Clare Rodger. “Today, we’re excited to invite ‘Masters of the Universe’ fans to become heroes in the real world. Heroism doesn’t stop at the screen, and this campaign shows how every action can help shape brighter futures and better outcomes for children across the U.S. and around the world.”

Galitzine took to Instagram in June to announce the film had wrapped shooting. “It has been an honor shouldering the responsibility of playing Adam and He-Man,” he wrote. “It’s been the role of a lifetime and I put everything into it. There’s not much I can show you, but I am so proud of the movie we’ve made. Thanks to our amazing cast and crew for all your hard work.”

Mendes plays Teela in the movie, while Elba takes on the role of Duncan. The movie is an adaptation of the 1983 animated series. “Bumblebee” director Travis Knight helms the film with a script from Chris Butler.
