Star Rutger Hauer) has said of this movie on his official website: "Blind Fury (1989) was one of the most difficult jobs for me because of the combination with the swordplay. I'm glad it does not show. I mean that is was so difficult. Trained a month with a blind man who taught me his handicap. He was such a nice man. First thing he said was, 'I don't get confused about what I see...'. Then I trained every morning at 4:30 [am] before shooting for those seven weeks. Then Shô Kosugi was brought in for the swordplay. That was an additional shoot for a week or so. Wonderful."
Tim Matheson was introduced to producer Daniel Grodnik by writer Charles Robert Carner. Matheson was interested in learning how to produce. Grodnik said to him if you ever bring me a piece of material that I like, you can be a producer on it with me. Two weeks later Matheson screened "Zatoichi Challenged" (Zatôichi chikemuri kaidô (1967)) for Grodnik to develop as an American remake. It took two directors, three studios, seven years, and eleven drafts of the screenplay, to finally get the movie about a blind samurai in America made. Grodnik sold it to Jeff Sagansky, the president of Tri-Star Pictures, by pitching him two ad lines: "He don't need no dog" and "Pray you see him before he hears you". The main tagline in the end used on American movie posters was similarly: "He may be blind but he don't need no dog."

The movie's source Zatoichi film of which it is a remake is Zatôichi chikemuri kaidô (1967) this being the seventeenth film in the Japanese franchise known as the "Blind Swordsman" series.
