In “Dark Command”, Pidgeon played William Quantrill [why the misspelling, who knows]. For reasons beyond bizarre, they decided to premiere the movie in Lawrence, Kansas [featured in the movie], which Quantrill largely destroyed [along with murdering approximately 162 men and boys] in the summer of 1863 [when it was the capital of Kansas.
I notice that the studios did that frequently with their high profile productions. "Gone With the Wind" had an early premier in Atlanta. "Dodge City" had an early premier in, of course Dodge City. The current issue of Life magazine has a spread on an appearance by the stars of "Virginia City" in that location. (It didn't mention a premier - maybe there was no theatre in town then.) Anyhow, the New York premier of "Dark Command" won't be until April 15. I didn't see a review on Tuesday the 16th, but maybe there will be one later in the week. I never suspected Roy Rogers and John Wayne ever appeared in the same film.
