Ross Martin's Chan film. It has been a long time since I saw it. As I recall, Ross played it really "Grin and bow". That is to say he overplayed the stereotype a good bit. Kind of like J. Carrol Naish's portrayal or the radio actors you might've heard such as Ed Begley. The story was a typical 1970s TV movie. Solid in plot and direction. I don't recall specifics of the story or solution. Ross Martin, being the fine performer he was, did a credible job. It was, as best I remember, worth a watch.
