From the information I have seen, Edwin Luke was in one film, PERIOD. It could be that his older brother, Keye, had heard that Monogram Pictures was looking for a Chan son for one movie. Maybe, on something of a lark, Edwin gave it his best shot. In watching "THE JADE MASK," it has to be admitted that the younger Luke brother was far from Academy Award caliber, although, in my humble opinion, he gave an adequate performance as Edward "Eddie" Chan.
