Hi David. Please excuse my ignorance. I had read that post and seen the explanation of takemusu leading to seven virtues but hadn't seen it as the seven virtues of budo. Perhaps I should have noted more carefully the next line which said it can be found in bushido.
Secondly you are right again, I have named the wrong film, the one with the samurai who is also a karate master is called I believe the fist of legend.
