Mattel’s Masters of the Universe was first introduced to the world in 1982 through a line of popular action figures. In 1983, the treasured animated series He-Man and the Masters of the Universe premiered and became one of the first children’s programs to be syndicated on television. From its inception, the MOTU brand was built upon the message of becoming the best version of oneself, and today, the franchise spans a variety of consumer touchpoints across toys, television, video games, and more.

Mattel Films’ vision is to collaborate with leading filmmakers to make standout quality movies based on our iconic brands that will resonate in culture and appeal to global audiences. Including Masters of the Universe, Mattel Films has 15 live-action motion pictures in active development including American Girl, Hot Wheels, Bob the Builder, Magic 8 Ball, Matchbox, Major Matt Mason, Polly Pocket, Barney, Rock ‘Em Sock ‘Em Robots, Thomas & Friends, UNO, View-Master, and Wishbone. Mattel Films is also developing Christmas Balloon, a holiday family drama based on all-new IP.
