Battle Angel, known in Japan as Gunnm , is an original video animation based on the Battle Angel Alita manga by Yukito Kishiro. The OVA comprises two episodes, Rusty Angel and Tears Sign, that serve as a compressed preview for the manga. They correspond respectively to volumes 1 and 2 of the manga, with some differences. According to Kishiro, only two episodes were originally planned. At the time, he was too busy with the manga "to review the plan cooly [sic]", nor was he serious about an anime adaptation. He has no plans to revive the anime. A big budget Hollywood movie version of the story is scheduled to be released on December 21, 2018.
