John Stevenson, the co-director of "Kung Fu Panda," has felt the power of Grayskull, signing on to direct "
Masters of the Universe," Warner Bros. and Silver Pictures' live-action version of the popular 1980s cartoon and toy line.
The show, made in partnership with toy company Mattel, was known for the image of blond-haired Prince Adam on top of a mountain uttering the magic words, "By the power of Grayskull, I have the power," and turning into the heroic He-Man. He-Man and his allies -- Battle Cat, Man-at-Arms and Orko -- defended their planet Eternia from the evil forces of Skeletor, who tried week after week to conquer a fortress known as Castle Grayskull, which imbued He-Man with his powers.
