I'm wondering if they decided at some point to make a comedy of it. Some of those lines can't be meant to taken seriously. Darren McGavin was a fine actor. Surely he, Cotten and Carey are playing for laughs. Carey is so wooden that you can't imagine anyone following him into battle. One of the writers is so embarrassed he is credited as Fred C. Dobbs. Iron Eyes Cody was "technical adviser" - he was an Italian! Hilarious.
