Since the debut of the Dragon Ball anime series, Toei Animation has been producing feature films based on the franchise since 1986. Seventeen feature films were produced, including three films based on the original Dragon Ball anime, thirteen films based on the sequel series Dragon Ball Z, and seventeenth film commemorating the tenth anniversary of the series.
