The tattoo on Briareos' left upper arm says "Cogito Ergo Sum", which is Latin for "I think, therefore I am." Strangely, Greek characters are used and not Roman. Also the first character is Gamma, but C would rather be transliterated as Kappa in Greek. It also has the dates 2096-2122, which are Briareos' date of birth and date of his "death" when he became a cyborg.
The film takes place in 2131.
Miuccia Prada from the fashion house that bears her name was a big fan of the film and even designed the costumes for the sequel.
Initially licensed by Genenon, the film was dubbed into English by Animaze. When the license went to Sentai Filmworks several years later, they redubbed it using the voice cast from the sequel, Appleseed: Ex Machina (2007).
Released a decade before the reboot "Appleseed Alpha".
