Daredevils of the Red Circle

This Republic serial is about as good as they get. The chapter ending involving a tunnel under the river is quite memorable, as I pass through the Lincoln Tunnel every morning on the way to work.

I was also impressed with the always-excellent Charles Middleton (best remembered as Ming the Merciless) as the villain. Everytime we see him in a movie, my girlfriend gasps "39013!"...which is pretty remarkable when you think about it. How many numerically-named characters do YOU remember from old movies?
