Variety reports that Thor 2 scribe Christopher Yost is now on board to do a rewrite on Masters of the Universe. One assumes that a rewrite means Yost won’t be starting over from scratch, but simply picking up where the other writers left off.
No word on the storyline either, though presumably the script will follow the same outline as the animated series, which aired between 1983 and 1985. Set on the planet of Eternia, Prince Adam has the power to transform himself into He-Man, the strongest man in the universe. He uses his powers to fight Skeletor and stop the villain from conquering Castle Grayskull.
