Rage at Dawn, Full western, Cowboy.

Rage at Dawn is a 1955 American Technicolor Western film directed by Tim Whelan, and starring Randolph Scott, Forrest Tucker, Mala Powers, and J. Carrol Naish. It purports to tell the true story of the Reno Brothers, an outlaw gang which terrorized the American Midwest, particularly Southern Indiana, in the period immediately following the American Civil War.

A more successful version of the Reno brothers' story was released the following year as Love Me Tender, starring Elvis Presley as Clint Reno.
