Screenwriter Richard Wenk has signed on to rewrite the script for Masters of the Universe. He will be working from the original draft by Alex Litvak and Michael Finch (Predators).

The story follows He-Man, a young warrior trying to defeat the nefarious Greyskull to save his magical world. We reported in July that Jon M. Chu (G.I. Joe Retaliation) will direct.

Todd Black, Steve Tisch, and Jason Blumenthal are producing through their Escape Artists company. Sony Pictures will distribute, although it isn't known when production will begin.
