I've searched every reliable 情報源 all over the internet and even on Lionsgate's page, there is no sign of a sequel to this movie anywhere. 表示する us a link if あなた think it is reliable, and Wikipedia does not count.
i am gonna be soooo pissed if 2012 happens and i don't get to watch the 次 A&O movie... but yeah i think lionsgate and crest animations are the companies doing it
