"Song of Old Wyoming" is the first of a series of B-Westerns, starring Eddie Dean and filmed in Cinecolor by Poverty Row studio, PRC. A total of five were produced in color.
The story is that Eddie Dean was upstaged in this first of the series by newcomer, Al (soon to be known as "Lash") LaRue. LaRue couldn't sing like Eddie Dean, who was the most mellifluous of cowboy singers. Dean also co-wrote two of the films three songs.
Prolific B-movie producer-director, Robert Emmett Tansey, produced the initial entries in Dean's series at PRC.
Cinecolor was a two-color process using blue-green and red-magenta dyes. The system produced acceptable color at a fraction of the cost of Technicolor. Cinecolor reproduced reds, browns and blues well and for this reason was used on many westerns.
