The project has been at Paramount on-and-off since 2003 and at one point even had Darren Aronofsky attached to direct.
Last year’s round of chatter described the movie plans as a remake of 1993’s Kozure Okami: Sono Chisaki Te Ni (Lone Wolf and Cub: Final Conflict).
A project for a live-action adaptation of Kazuo Koike and Goseki Kojima’s Lone Wolf and Cub samurai manga is currently at Paramount with Star Trek Beyond director Justin Lin (also known for The Fast and the Furious 3–6) still onboard to produce and possibly direct.
