The film opened in Japanese theaters in 2003. Its premiere followed in the footsteps of the popular
Sky High television series, starring the same actress (
Yumiko Shaku) in the lead role of Izuko—or specifically, the "new" Izuko, as the film is considered a
prequel to the
TV series, revealing how Mina Saeki (Shaku) came to replace the previous Guardian and take her position as the Izuko we see in the series. Although the film makes much greater use of action, martial arts, and big budget special effects than the series is capable, both follow the same continuity.
TV-Asahi, the Japanese television network behind the
TV series is also the theatrical film's primary production company. The movie was helmed by popular action director
Ryuhei Kitamura, best known for his
Versus series of films, as well as other popular draws such as
Azumi and
Godzilla: Final Wars. Kitamura also directed several episodes of the TV series, and following the film's box office success,
Sky High 2 (or Season 2) was quickly put into production by the network for January 2004, utilizing many elements from the film, including its darker, edgier look, and improved sets and effects. The film's
screenplay was written by
Isao Kiriyama, based on the manga
Sky High by
Tsutomu Takahashi. The closing theme for the movie is "Horizon" by
Hyde (
L'Arc-en-Ciel and
Vamps). ==References==
