Joel Silver & Warner In 'He-Man' Talks

Warner Bros. Pictures and Joel Silver are trying to get the power of Grayskull.

The studio and producer are in negotiations with toy company Mattel to acquire the rights to one of the most popular cartoons of the 1980s, "He-Man and the Masters of the Universe," with plans to bring a live-action version to the big screen.

The cartoon 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.
