The box office success of Barbie has led parent company Mattel to pursue a fleet of film adaptions based on its toys. Some of these range from the obvious (both Hot Wheels and Matchbox feel like they could fit the same vibes as the Fast & Furious saga) to the ridiculous (how on Earth can anyone make a film out of Uno?) While arguments could be made that Mattel has taken away all the wrong lessons from Barbie‘s success, there’s one property that the toy giant seems to have run into trouble with — He-Man and the Masters of the Universe.
