 As a bonus for audiences who attended the Japanese theatrical run of  the film, Studio Madhouse animated a special short music video based  on another of CLAMPs manga series: Clover. The short, which was  directed by Kitaro Kousaka, has not been shown at any other time and  remains unavailable home video and DVD due to legal issues between  the studio, the group which provided the song (ALI Project), and the  financiers. The short is mentioned, however, in some of the Japanese  language commercials on the Cardcaptor Sakura: The Movie DVD.
