After helping shape the world of Asgard, “Thor” scribe Christopher Yost is now ready to head to Eternia to help He-Man return to the bigscreen.

Sony Pictures and Escape Artists have tapped Yost to do a rewrite on its reboot of “Masters of the Universe.”

Terry Rossio and Jeff Wadlow wrote previous drafts of “Masters of the Universe,” which is being produced by Escape Artists principals Todd Black, Jason Blumenthal and Steve Tisch along with DeVon Franklin.

Set on the planet of Eternia, the story follows a warrior named Prince Adam who has the power to transform into the heroic He-Man. His nemesis is a villain named Skeletor who seeks to conquer a fortress known as Castle Grayskull in order to learn the secrets held within.
