One of the first examples of a "sleeper"--a film shot inexpensively, with no name stars and with no great expectations for it, which turns out to be a huge critical and commercial hit.
Bud Abbott and Lou Costello awarded "Promise" the Boscar, a fire hydrant-shaped award, for Best Male Dog Actor of 1940 for his work in this film. Promise also attended the Second Annual Tailwaggers Dinner held at Charley Foy's Club.
One of filmed two dog stories by source writer James Street who also penned the source novel of Good-bye, My Lady (1956). There are two versions of Street's other dog story, The Biscuit Eater (1940) and The Biscuit Eater (1972).
Apparently, the first sound movie to be filmed entirely on location, at least in the state of Georgia, USA.
The film was made and released only about a year after it source short story by James Street had been first published in 1939.
