The location filming at the end of the movie (the film on which Skipper is a laborer) is being done at Copper Creek, a tributary of the Klamath River, which runs primarily through Trinity County, California. The location is called "Copper River" in the film; though it is technically called Copper Creek in reality. Sometimes the creek does get called Copper River by some.
The prison set where Bob and Skipper perform the staged fight is the reformatory built for The Godless Girl (1928).
Bruce Cabot has only one line: "Well, fifty bucks is fifty bucks." He would do a little better that year with "King Kong".
This film was a mild success at the box office, earning RKO a profit of $65,000 (over $1.56M in 2023) according to studio records.
