 That was the first Commando Cody. My other favorite serial was Drums of Fu Manchu with Henry Brandon playing the evil Oriental. I don't know if you've ever seen that, but if you never have, you will. I'll seek it out. And finally, Daredevils of the Red Circle, 1939, with the fellow who played Bing the Mercer, Charles Middleton, playing 39013. That was his villainy.
