The film stars Dolph Lundgren, Frank Langella, Jon Cypher, Chelsea Field, Billy Barty, Courteney Cox, Robert Duncan McNeill, and Meg Foster. It is based on the Mattel toy line of the same name and tells the story of two teenagers who meet He-Man, the most powerful man in the universe, and his friends, who arrive on Earth by chance from their home planet Eternia and go on a mission to save the universe from He-Man’s archenemy, the evil Skeletor. Masters of the Universe was released theatrically in the United States on August 7, 1987. It was a critical and commercial failure, grossing $17 million worldwide against a budget of $22 million, but is now regarded as a classic cult film. Plot On the planet Eternia, Skeletor's army seizes Castle Grayskull, scatters the remaining Eternian defenders, and captures the Sorceress of Grayskull, planning to seize power over the entire universe by the next moonrise. Skeletor's archenemy, the warrior He-Man, veteran soldier Man-At-Arms and his daughter Teela rescue Gwildor from Skeletor's forces. Gwildor, a Thenorian locksmith, reveals that Skeletor has acquired his invention: a "Cosmic Key" that can open a portal to anywhere by utilizing musical notes. The device was stolen by Skeletor's second-in-command, Evil-Lyn, allowing Skeletor to breach Castle Grayskull. With Gwildor's remaining prototype of the Key in hand, He-Man and his friends travel to the Castle. They attempt to free the Sorceress but are overwhelmed by Skeletor's army and forced to flee through Gwildor's hastily opened portal, transporting them to Earth. The Key is misplaced on their arrival and discovered by two California teenagers, orphaned high school girl Julie Winston and her boyfriend Kevin Corrigan. While experimenting with the device, they accidentally send a signal that allows Evil-Lyn to track it. She then sends her henchmen Saurod, Blade, Beast Man and Karg to recover it. Kevin, an aspiring musician, mistakes the Key for a synthesizer and takes it to a music store run by his friend Charlie. Karg's team arrives and chases Julie until He-Man rescues her. Karg's team returns to Grayskull where, incensed by their failure, Skeletor kills Saurod and sends the others back to Earth, with a larger force under Evil-Lyn's command.
