Inspiration for Lone Wolf and Cub?
I know it's a bit of a long shot, but it did occur to me at the end of SAMURAI REBELLION, with Mifune walking away from the village carrying the baby in one arm and his sword in the other, that the image may have sparked the idea for Lone Wolf and Cub in Kazuo Koike's mind back in 1954 ...
Not a big deal, but just something that occurred to me :-)
