Battle Angel (銃夢, GUNNM?) is an OVA based on the Battle Angel Alita (known as GUNNM in Japan) manga by Yukito Kishiro. The OVA is comprised of two episodes, Rusty Angel and Tears Sign, that serve as a compressed preview for the manga. The OVA spawned a memorable soundtrack including the theme song and "Cyborg Mermaid". Although it received a lukewarm reception in Japan, U.S. critics held it to be one of the best anime to be translated and brought to America in the 1990s. The UK version is just a single movie.
