Stagecoach (1939) - A group of traveller’s, all different in occupation and standings, travel through the New Mexico territory in 1880. The passengers must battle with an outlaw-kid (played by John Wayne in his breakout role) and ever present Apache attacks. This is the first film of many shot by John Ford in Monument Valley.
W.R. Hearst commanded all of his publications to neither condemn nor promote the film as a gesture towards the friendship between the Hearsts and the Welles families. Since Hearst had a near monopoly on U.S. publications in print across the states, it was perceived as a dud film by the public as they couldn't garner a review either way. Remember now, these were times when people relied on papers for their news and pennies were short. Too short to waste on a film with no review from their only news sources.
The film opened to mixed reviews and exclusive theaters anti-Hearst promotions. It still profited. It was only after W.R. Hearst and Howard Hughes' deaths that the film actually gained any notoriety. It's a good film for the history of its back story. Not for it's exclusive artistry.
