Masters of the Universe has received major praise from the President of Mattel Studios, but is this just hype for the movie, or can it be believed? Masters of the Universe is Mattel’s second major live-action feature film, following the massive box office and cultural sensation that was Barbie. Travis Knight, who previously directed Bumblebee for Hasbro, will helm Masters of the Universe with Nicholas Galitzine starring as He-Man.
