Tom Betts at the SWDB:"The Antonio Prieto who played Don Miguel Benito Rojo was Anonio Prieto Puerto who was born in Aspe, Spain in 1914 and diedof a heart attack in Madrid, Spain on March 3, 1965. This makes more sense as the recently deceased singer, actor is only 4 yearsolder then Clint Eastwood and the actor playing Don Miguel looks to be a much older actor."
so he was 50 when FOD was filmed... that sounds more like it
