While talking to my father about a Sonny Chiba movie, I was suddenly reminded of this. I think I had only heard it mentioned by Patrick Macias in Tokyo Scope, or something.
It's an (old?) Japanese series called the something-something-something of Muhammad. (I think.)
All I can remember is that it was a Japanese live action series, I think it had "Muhammad" in the title, and it had a now famous Japanese actor (I think it was Sonny Chiba) playing the Islamic prophet Muhammad.
Thanks to anyone who can hep on this one.
