This movie was seen in Japan in 1963 by author Roald Dahl, from which he got several ideas for the writing of the screenplay to the James Bond movie You Only Live Twice
(1967). The scene where Goemon attempts to assassinate Nobunaga with poison was referred to in "You Only Live Twice" and "Grosse Pointe Blank". Several scenes shows Nobunaga petting his cats. This is also done by the villain Blofeld in "You Only Live Twice". See more
