Plenty of the familiar 'B' western conventions are to be found here - a wrongly accused hero pursued by the law, a map marking the location of a gold mine, a glamorous tomboy heroine, a couple of cute horses, and so on. But 'Relentless' also makes immaculate use of the 'A' movie trappings of a good cast, a moody atmosphere and - above all - magnificent Technicolor photography of Arizona shot by cameraman Edward Cronjager; particularly the snowscapes that serve as an imposing backdrop to the early scenes.
