There is no need to review this serial as it has already been reviewed pretty good already. Just wanted to add a few comments. Am I the only one to see the Alfred Hitchcock influence in the serial? At the end of Chapter one we can see our hero falling out of a plane having problems with his parachute. There are semi-closeups with him flailing his arms. This technique was done in 1942 by Alfred Hitchcock in "Saboteur" when the villain played by Norman Lloyd falls from the Statue of Liberty. Hitchcock used it again in "North By Northwest" when one of the baddies falls from the "monument" in South Dakota. Then there is the outright scene taken from Hitchcock's "Foreign Correspondent." This happens several chapters into the serial. There are a number of people on a clipper. It is shot at by a submarine. We see the plane falling apart. Then we are behind the two pilots when the nose of the plane strikes the ocean and water gushes in. Hitchcock in one of his interviews tells how h did that camera trick.
