This film was the third Oscar win for Walter Brennan, who won three out of the five best Supporting Actor Academy Awards. Despite being nominated the subsequent year for Sergeant York (1941), also with Gary Cooper, he was never nominated again in a very long career.
According to the New York Times review of the film on 25 October 1940, it opened at the Radio City Music Hall the night before, more than one month after the national opening on 20 September 1940. No reason was given for the apparent delay. Their credited cast list also is identical to the one in the AFI Catalog, including the character name of "Burt Cobble" for Dana Andrews. However, Variety's cast list has Andrews' name correctly as "Hod Johnson," so there is still a mystery concerning which are the original credits.
