Sony Pictures has brought on Thor: Ragnarok screenwriter Christopher Yost to take a crack at the Masters of the Universe script, according to a new report at Variety. The project has been in development for years, but fans hoped that it may finally get off the ground earlier this year, when the studio released a new Masters of the Universe logo, and it was revealed that Jeff Wadlow's (Kick-Ass 2) script was complete. It seems the studio is going back to the drawing board with yet another writing coming on board.

The franchise is set on the planet Eternia, following a young man named Adam who has the power to turn himself into a mighty warrior named He-Man. Adam becomes the planet's last hope to defeat the evil Skeletor, who has devastated the entire planet on his quest to conquer castle Greyskull. It isn't known how much the plot of this adaptation will be altered with another writer on board, or whether it will be set on Earth or Eternia.

Masters of the Universe was first launched as a toy line from Mattel in 1982, which quickly spawned He-Man and the Masters of the Universe, an animated series that debuted in 1983. The spin-off She-Ra: Princess of Power debuted in 1985, with the Masters of the Universe live-action feature debuting in 1987, starring Dolph Lundgren as He-Man and Frank Langella as the nefarious Skeletor.

Throughout the years, writers such as Evan Daugherty (Divergent), Alex Litvak and Michael Finch (Predators), Richard Wenk, Terry Rossio and Jeff Wadlow have been attached to the project. The director's chair has been a revolving door as well, with John Stevenson (Kung Fu Panda), and, most recently, Jon M. Chu set to direct. Escape Artists' Todd Black, Jason Blumenthal and Steve Tisch are producing.

Christopher Yost started his writing career on the small screen, working on animated shows such as X-Men: Evolution, Fantastic Four: World's Greatest Heroes, Teenage Mutant Ninja Turtles, The Avengers: Earth's Mightiest Heroes and Iron Man: Armored Adventures. After writing the animated feature Hulk Vs., and doing some uncredited work on the first Thor, he was brought in to write the script for 2013's Thor: The Dark World. He is currently writing Thor: Ragnarok with Craig Kyle.
