The film, which sees Batman sent back in time during medieval-era Japan, will be released sometime next year on DVD and Blu-ray.
Batman Ninja is being directed by Jumpei Mizusaki (JoJo’s Bizarre Adventure) with character designs by Takashi Okazaki (Afro Samurai). Eric Garcia and Leo Chu wrote the English screenplay, which is based on a script by Kazuki Nakashima.
