The Fighting Devil Dogs (1938) is a 12-chapter Republic movie serial starring Lee Powell and Herman Brix, the latter better known by his later stage name, Bruce Bennett. It was directed by William Witney and John English. While not often considered one of the best serials ever made, as it contains a lot of stock footage and two recap chapters, it is famous for its main villain, The Lightning—the very first costumed supervillain. There is some speculation that George Lucas used The Lightning as a template for Darth Vader.
