Although Burt Sullivan (Franco Nero) is portrayed as roughly seven years older than his brother Jim (Alberto Dell'Acqua), Dell'Acqua is in fact three years Nero's senior.
In Germany, the film was retitled as 'Django Der Racher' which in English means 'Django the Avenger'. It doesn't actually star the Django character, but after 'Django' 1966 was a global sensation, many westerns, especially starring Django's actor, Franco Nero were retitled to make more money and profit off of the fresh Django craze.
Shot in April and May of 1966.
