There's a reason Westerns never get old. They're set in a small part of the world, chronicling events between long-gone men in strange costumes. But the concepts they elaborate on pertain to any country or social circumstance. The director and actors of this classic are as iconic as they come, but John Wayne's gun-loving attitude accurately portrays NRA's current stance on fighting crime, and Jimmy Stewart's law-abiding position is considered the doctrine for any non-violent movement. Add Lee Marvin, Vera Miles and Lee Van Cleef, and this is one of those black-and-whites you'd want to watch, and enjoy the trance.
"This is the West, sir. When the legend becomes fact, print the legend."
PS: Amazing. Vera Miles is still around.
