"The Feathered Serpent" is the only Charlie Chan film featuring both Keye Luke and Victor Sen Yung together as Charlie's sons. Charlie here is portrayed by Roland Winters. He does a very good job, but I prefer Warner Oland in the role. He was also so warm and cheerful. Toler was very good, but more sardonic and sarcastic.
In this film, Charlie and two of his sons are asked to investigate a gang who has kidnapped an archaeologist to force him to search for a treasure in Mexico.
Mantan Moreland plays Charlie's chauffeur, Birmingham. I know his characterization is not politically correct today, but what a funny and talented man he was. I always enjoy him in these films.
By this time, Charlie Chan films were being made at a poverty role studio. As offensive as they are today, I take them for what they were and like them. We cannot view everything from today's viewpoints.
