The Vigilante Serial

 

Clipped from Wikipedia: The Vigilante (1947) was the 33rd serial released by Columbia Pictures. The Vigilante was originally a comic book character whose first appearance was in Action Comics (Issue #42, November 1941) and starred Ralph Byrd, well known for his central role in the Dick Tracy serials. It was his last ever serial appearance.

The Vigilante was a singing-cowboy radio performer who doubled as a motorcycle-riding crime-fighter along with a pre-teen Chinese boy, Stuff the Chinatown Kid.

In the serial version, Stuff became a white, draft-age sidekick played by George Offerman Jr. Ralph Byrd was cast as the Vigilante. Director Wallace Fox makes a cameo appearance as the director filming Greg Sanders' movie at George Pierce's ranch.
