As Boris Karloff moved on to bigger and better things in the horror film genre, the Mr. Wong series from Monogram got a final run with an actual person of Oriental heritage in the title role. Fascinating the mind set of Hollywood in those days.
And who would it have to be for, but a poverty row outfit like Monogram in one of their series films. Keye Luke who moviegoers knew better as the number one son of that other Chinese detective Charlie Chan, gets to play a younger version of that noted scholar and criminologist James Lee Wong. Luke plays him just as Boris Karloff did as a man who went to both Oxford and Heidelburg and did not speak in fortune cookie aphorisms.
But I'm sure it must have confused the living daylights out of the Mr. Wong audiences when the relationship between Wong and homicide police captain Street of the SFPD was so different. Grant Withers played Street in all the Wong films and he was not at all resentful about deferring to the older man's knowledge. The same way Captain Stottlemeyer defers to Adrian Monk on that show.
But with Luke, Withers is at first downright hostile, in fact this film of necessity is set back to when they first meet and Withers most reluctantly bows to Luke's skill for investigation.
The leader of an expedition to China where an ancient scroll was taken from a Ming Emperor's tomb is murdered while giving a lecture. And the scroll goes missing as well. There are a whole host of suspects, including a pilot that had been lost in the desert, but he turns up rather early in the film.
It might have been nice if Keye Luke had inaugurated the series instead of an Occidental like Karloff, good as he was. History could have been made.
