Frank McGlynn Jr., Ethel Wales and Thomas Pogue are in in studio records/casting call lists for unspecified roles but were not seen in the movie.

This film is listed in the copyright registry as "The Eagle's Blood" and was reviewed by Variety under that title.

The on-screen credits reads "Clarence E. Mulford's 'The Eagle's Brood'" suggesting Mulford wrote the story, since no title by that name was ever published.
