Several trade papers and national magazines noted that the film set a record for the number of screenwriters who worked on the script. Beside the 4 given credit onscreen, at least 13 others were involved.
David Niven played the role of a "British Diplomat" during filming, and Benita Hume also was "Mary Smith's Stepmother." However, both roles were eliminated before release.
Arthur Hoyt is in studio records/casting call lists as "Valet," but he did not appear in the movie.
Modern sources also list Billy Wayne, Ernie Adams and Jack Baxley as Rodeo Riders, but they did not appear or were not identifiable in the movie.
During the film's production, news items listed Iron Eyes Cody, Silver Tip Baker, Steve Clemente, John Judd and Danny Borzage in the cast. None of these actors, however, have been confirmed.
