This film skirted the Production Code by making several not to subtle hints that Mr. Brown's henchmen, Fante and Mingo (played by Lee Van Cleef and 'Earl Holiman'), were a homosexual couple.
The names 'Fante' and 'Mingo' were later used by writer-director Joss Whedon for two characters - twin brothers - that the Serenity crew meet in the movie Serenity (2005).
