Sam Peckinpah - according to Maureen O'Hara (who had survived five films with that cantankerous old cuss John Ford) "one of the strangest and most objectionable people I had ever worked with" - got his break in feature films at the behest of Brian Keith, with whom he had just worked on five episodes of the TV series 'The Westerner' (and like Dean Martin in 'Some Came Running' always keeps his hat on).
Set in 1867 and shot on a twenty day schedule on location in Arizona with the camera safely in the hands of veteran cameraman William Clothier, Sam's inexperience with the big screen (and the choppy cutting that resulted) and that O'Hara was in reality having such a miserable time probably enhanced the bleak and sardonic quality of the rambling film that emerged; while Marlin Skiles' relentless guitar, accordion & harmonica score - for good or ill - stays with you (as does Miss O'Hara's full-throated rendering of the song that accompanies the opening & closing credits).
A small, interesting cast includes jug-eared veteran Will Wright in one of his last films, and future Peckinpah regular Strother Martin.
