Columbia Pictures originally purchased Lewis R. Foster's unpublished story, variously called "The Gentleman from Montana" and "The Gentleman from Wyoming", as a vehicle for Ralph Bellamy, but once Frank Capra came on board as director – after Rouben Mamoulian had expressed interest – the film was to be a sequel to his Mr. Deeds Goes to Town, called Mr. Deeds Goes to Washington, with Gary Cooper reprising his role as Longfellow Deeds.[N 1] Because Cooper was unavailable, Capra then "saw it immediately as a vehicle for Jimmy Stewart and Jean Arthur",[11] and Stewart was borrowed from MGM.[4] Capra said of Stewart: "I knew he would make a hell of a Mr. Smith ... He looked like the country kid, the idealist. It was very close to him."[12]
Although a youth group is featured in the story, the Boy Scouts of America refused to allow their name to be used in the film and instead the fanciful "Boy Rangers" was used.[4]
In January 1938, both Metro-Goldwyn-Mayer and Paramount Pictures submitted Foster's story to the censors at the Hays Office, likely indicating that both studios had an interest in the project before Columbia purchased it. Joseph Breen, the head of that office, warned the studios: "[W]e would urge most earnestly that you take serious counsel before embarking on the production of any motion picture based on this story. It looks to us like one that might well be loaded with dynamite, both for the motion picture industry, and for the country at large." Breen specifically objected to "the generally unflattering portrayal of our system of Government, which might well lead to such a picture being considered, both here, and more particularly abroad, as a covert attack on the Democratic [sic?] form of government", and warned that the film should make clear that "the Senate is made up of a group of fine, upstanding citizens, who labor long and tirelessly for the best interests of the nation."
Later, after the screenplay had been written and submitted, Breen reversed course, saying of the film, "It is a grand yarn that will do a great deal of good for all those who see it and, in my judgment, it is particularly fortunate that this kind of story is to be made at this time. Out of all Senator Jeff's difficulties there has been evolved the importance of a democracy and there is splendidly emphasized the rich and glorious heritage which is ours and which comes when you have a government 'of the people, by the people, and for the people.'"[4]
The film was in production from April 3, 1939, to July 7 of that year.[13] Some location shooting took place in Washington, D.C., at Union Station and at the United States Capitol, as well as other locations for background use.[14]
In the studio, to ensure authenticity, an elaborate set was created, consisting of Senate committee rooms, cloak rooms, and hotel suites, as well as specific Washington, D.C., monuments, all based on a trip Capra and his crew made to the capital. Even the Press Club of Washington was reproduced in minute detail,[4][15] but the major effort went into a faithful reproduction of the Senate Chamber on the Columbia lot. James D. Preston, a former superintendent of the Senate gallery, acted as technical director for the Senate set, as well as advising on political protocol. The production also utilized the "New York street set" on the Warner Bros. lot, using 1,000 extras when that scene was shot.[4]
The ending of the film was apparently changed at some point, as the original program describes Stewart and Arthur returning to Smith's hometown, where they are met by a big parade, with the implication that they are married and starting a family.[4] In addition, the Taylor political machine is shown being crushed; Smith, riding a motorcycle, visits Senator Paine and forgives him; and a visit to Smith's mother is included. Some of this footage can be seen in the film's trailer.[16]
