Látigo

The train in the opening credits and closing scene is Colorado's Durango & Silverton Narrow Gauge Railroad, which was then the Denver and Rio Grande Western. In 1971 the DRGW was still owner and operator of the line, and this track was still part of a class 1 railroad and not a tourist / heritage railroad. Even though DRGW was looking at the time for a buyer or just the permission to the interstate transportation board for abandonment of the rail grade. They would find neither until the mid 1980s. The scene was reused a year later in the italian western comedy Y después le llamaron el magnífico (1972).

In the bar fight, Patience sees Latigo lying face-down on the floor with nobody near him. In the close-up, Latigo's lying face-up with his head on the leg of another unconscious cowboy.
