No, Jackie came later (or at least, came later to North America).
Besides, this actor could actually speak English.
I may be wrong about the Magnum connection. He only guest starred there.
Yet I can see the actor playing a nice guy on some show, this is going to
nag me. He's also played some "bad guy" roles, ie in the Japanese army
during WWII.
It was Clyde Kusatsu, the name doesnt' ring a bell, but his face does.
