Holt of the Secret Service 1941 was the 16th serial released by Columbia Pictures.
The brains heavy is a man named Lucky Arnold but he hides behind the facade of one of his loyal henchmen, Quist, to shield himself from the Secret Service, and lets another one of his men, Valden, do most of his dirty work. The island nation has its own pocket dictator who is also trying to rub out our hero. During theepisodes, Holt endures numerous brushes with death, emerging from all of them with nary a hair out of place nor a crease in his welltailored business suit.In this serial, Jack Holt strictly played himself with all the gimmicks he had used at silent and talkie movies still very much in evidence. Producer Larry Darmour felt the serial was made for adults and not children by making it thrilling and logical but never impossible. He also felt that this was the first film with the lead actors name in the title. ........
