Amazon MGM Studios & Mattel Date ‘Masters Of The Universe’ For Summer 2026

The power of Greyskull is happening on June 5, 2026 when Amazon MGM Studios’ and Mattel Films’ finally bring their live-action reboot of Masters of the Universe to theaters.

As Deadline first told you, Bumblebee filmmaker Travis Knight is directing off Chris Butler’s screenplay (the initial draft written by David Callaham, and Aaron and Adam Nee). Mattel Films’ Robbie Brenner, and Escape Artists’ Todd Black, Jason Blumenthal, and Steve Tisch are producing.

The movie follows ten-year-old Prince Adam who 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 in the Universe.

The reboot has long been in the works at Sony, and then again at Netflix. It’s finally becoming a reality here at Amazon MGM.

Mattel’s Masters of the Universe was first introduced to the world in 1982 through a line of action figures. In 1983, the treasured animated series He-Man and the Masters of the Universe premiered and became one of the first children’s programs to be syndicated on television. From inception, the MOTU brand was built upon the message of becoming the best version of oneself and today, the franchise spans a variety of consumer touchpoints across toys, television, Netflix toon series, video games, and more. 

Amazon MGM Studios’ latest Zendaya movie, Challengers, from director Luca Guadagnino, is crossing $20M at the domestic B.O. today.
