Mattel provided financial backing for the show, as well as an accompanying toyline. The series premiered in 1985 and was cancelled in 1986, after 2 seasons and 93 episodes.On March 22, 1985, Filmation released an animated movie based on the series titled, He-Man and She-Ra: The Secret of the Sword.
