The Secret of the Sword, also known as He-Man and She-Ra: The Secret of the Sword, is a 1985 American animated superhero film produced by Filmation. Although released before the series She-Ra: Princess of Power began, the film was a compilation of the first five episodes with minor edits made. The film was part of a trend of theatrically released animated films created by producers of TV shows and toys during the 1980s. It is part of the same continuity as the He-Man and the Masters of the Universe cartoon series, and was created by the same Filmation production team and cast. It was the first He-Man theatrical film, and the first theatrical release to feature She-Ra or any Masters of The Universe/Princess of Power characters.
