High Quality Content by WIKIPEDIA articles! Dark Command is a 1940 western film starring Claire Trevor, John Wayne and Walter Pidgeon loosely based on Quantrill`s Raiders in the American Civil War. Directed by Raoul Walsh from the novel by W.R. Burnett, Dark Command is the only film in which western icons John Wayne and Roy Rogers appear together, and was the only movie Wayne and Raoul Walsh made together since Walsh discovered Wayne and gave him his first leading role in the widescreen western The Big Trail a decade before.
