Jane Wyman and Torchy Blane
Wyman's only performance of Torchy Blane was in "Torchy Blane ...Playing With Dynamite" which was released in August of 1939. It flopped.
However, in December of '39 "Private Detective" was released, starring Wyman, Dick Foran, Gloria Dickson and Maxie Rosenbloom.
It's obvious this was written as a Torchy Blane feature as Foran's Police Officer is identical with "Steve McBride" plus the fact that he and Wyman have been waiting to get married for five years. He even carries the wedding certificate around with him. Rosenbloom's "Brody" matches Tom Kennedy's "Gahagan" while Selmer Jackson's Agency Chief matches Newspaper Editor Joe Cunningham. Joseph Crehan's Police Chief matches that of Frank Shannon. It'a pretty obvious "Private Detective" was written to be a Blane feature but with the failure of "Torchy Blane ... Playing With Dynamite", the execs at the studio just changed a few names and went from there.
The original running time, by the way, of "Private Detective" was listed as 57 minutes but the print run by TCM runs only 55:24.
