Amazon MGM and Mattel Set June 2026 Release for Live-Action Masters of the Universe Reboot

Amazon MGM Studios and Mattel Studios have officially unveiled the first comprehensive teaser trailer for their upcoming live-action reimagining of Masters of the Universe. This high-stakes cinematic project is scheduled to hit theaters on June 5, 2026. Stepping into the director's chair is Travis Knight, the filmmaker celebrated for his work on the Transformers spin-off Bumblebee. This new iteration aims to breathe fresh life into the iconic 1980s franchise, specifically delving into the origin story of Prince Adam, portrayed by Nicholas Galitzine. The narrative explores his formative years, revealing that he spent fifteen years living on Earth before eventually discovering the legendary Power Sword.

The central storyline follows a character named Adam Glenn as he makes a triumphant return to the fractured world of Eternia. His mission is to challenge the oppressive reign of the notorious villain Skeletor, a role brought to life by Academy Award winner Jared Leto. According to the newly released plot details, the young Prince Adam was originally sent to Earth by his mother, Queen Marlena, played by Charlotte Riley, to ensure his survival during a catastrophic civil war that ravaged Eternia. Now an adult, Adam must reclaim his lost heritage and find his long-hidden artifact to unite a group of brave warriors. Together, they must protect the realm and prevent Skeletor from seizing control of the mystical Castle Grayskull.

This cinematic venture boasts an impressive ensemble cast supporting Galitzine and Leto. Camila Mendes stars as Teela, the daughter of the formidable Duncan, also known as Man-at-Arms, played by Idris Elba. The production also features Alison Brie as the cunning Evil-Lyn and Morena Baccarin as the Sorceress, while Kristen Wiig provides the voice for the character Roboto. The creative team has expressed a commitment to blending traditional fantasy elements with high-concept science fiction, offering a contemporary yet nostalgic perspective on the beloved universe. To bring this ambitious vision to the big screen, the project has been allocated a substantial production budget estimated to be between $170 million and $200 million.

This modern adaptation distinguishes itself from previous iterations, most notably the 1987 film starring Dolph Lundgren, by focusing heavily on Adam’s journey as a mature adult returning to his roots. The film emphasizes his quest to uncover the secrets of his lineage and his ultimate acceptance of his destiny as He-Man. The production is a collaborative effort between Metro-Goldwyn-Mayer and Mattel Studios. Distribution responsibilities are split between major players: Amazon MGM Studios will handle the theatrical release across North America, while Sony Pictures Releasing International has secured the rights for the film’s global distribution outside of domestic markets.
