Jean Arthur did not get along with James Stewart during filming, possibly because she had wanted her Mr. Deeds Goes to Town (1936) co-star Gary Cooper to be cast as Mr. Smith. Arthur thought Stewart was being deliberately a bit too cute for his own good and that Cooper was more masculine and had a stronger screen presence.
In 1942, when a ban on American films was imposed in German-occupied France, the title theaters chose Mr. Smith Goes to Washington (1939) for their last movie before the ban went into effect. One Paris theater reportedly screened the film nonstop for 30 days prior to the ban.
In his autobiography, Frank Capra states that after the film's general release, he and Harry Cohn received a cablegram from U.S. Ambassador to Great Britain Joseph P. Kennedy saying that he felt the film would damage "America's prestige in Europe" and should therefore be withdrawn from European distribution. In response, they mailed favorable reviews of the film to Kennedy, which persuaded him not pursue the matter any further, even though he still maintained his doubts.
The Washington press corps was highly indignant at the way it was portrayed in the film. Consequently, a great deal of the initial reviews from the capitol were very negative. One of their chief objections was that the film made them all out to be drinking too much.
James Stewart knew this was the role of a lifetime, one that could place him near the top of the Hollywood heap. Jean Arthur later remembered his mood at the time: "He was so serious when he was working on that picture, he used to get up at five o'clock in the morning and drive himself to the studio. He was so terrified something was going to happen to him, he wouldn't go faster."
To make his voice hoarse for the filibuster scene, James Stewart dried out his throat with bicarbonate of soda. However, both Frank Capra and Stewart revealed in interviews that his throat was periodically swabbed with mercuric chloride.
The film was banned in Nazi Germany, Fascist Italy, Soviet Russia and Falangist Spain. According to Frank Capra, the film was also dubbed in certain European countries to alter the message of the film so it conformed with official ideology.
The set for the Senate chamber was constructed on two newly built adjoining stages at Columbia, stage 8 and 9. The set was built almost to scale, and was at that time, the largest set built on a Columbia sound stage.
One reason Frank Capra made this film was to help him get over the loss of his infant son, who had died following complications from a tonsillectomy. Initially Capra wanted to make a film about Frédéric Chopin, but Columbia head Harry Cohn nixed that on the grounds that it would be too expensive. Capra and Cohn were constantly at loggerheads over budgets, despite Capra being Columbia's most successful director with--at the time--two Oscars under his belt.
Frank Capra and his crew went to Washington, DC, to film background material and to study the Senate chamber, which was replicated, full scale, in precise detail on the Columbia lot. James D. Preston, who was Capra's technical advisor for the Senate set and political protocol, was a former superintendent of the Senate press gallery.
The film's premiere was sponsored by the National Press Club in Washington, DC, at Constitution Hall with over 4,000 in attendance, including congressmen, Supreme Court Justices and Cabinet members. Frank Capra was seated next to Montana Sen. Burton Wheeler, who was one of many public officials who disliked the negative representation of Washingtonian politics, and left the theater midway through in a huff. Capra described the aftermath as "the worst shellacking of my professional life."
The screenplay was originally purchased by Columbia as a vehicle for Ralph Bellamy, with Harold Wilson slated to produce. Once Frank Capra became the director, the project, planned as a sequel to Mr. Deeds Goes to Town (1936), was entitled "Mr. Deeds Goes to Washington", and was to star Gary Cooper, reprising his role as Longfellow Deeds. Cooper was unavailable for the role, however, and James Stewart was borrowed from MGM. "I knew he would make a hell of a Mr. Smith," Capra said. "He looked like the country kid, the idealist. It was very close to him."
In 1941 Columbia was sued by Louis Ullman and Norman Houston, both of whom claimed that this film was plagiarized from their respective written works. Screenwriter Lewis R. Foster testified that he wrote the story specifically for Gary Cooper, and director Frank Capra testified that he had seen only the synopsis of Foster's story and had intended to use it as a sequel to Mr. Deeds Goes to Town (1936). Columbia won the case.
Information in the MPAA/PCA Collection at the AMPAS Library indicates that in January 1938, both Paramount and MGM submitted copies of Lewis R. Foster's story to the PCA for approval. Responding to a Paramount official, PCA Director Joseph I. Breen Jr. cautioned, "We 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 especially 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 form of government." Breen warned Columbia that the picture needed to emphasize 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," as opposed to "Senator Joseph Paine" and his cohorts. After the script had been rewritten, Breen wrote a letter to Will H. Hays in which he stated, "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.'"
The character of Harrison Paine was reportedly based on the then junior senator from Missouri, Harry S. Truman, then known as "the senator from Pendergast," for the political machine which backed his early career in politics. The capitol of Paine's and Smith's unnamed state is "Jackson City." The capital of Truman's state of Missouri is Jefferson City.
Frank Capra faced a daunting logistical problem in filming the Senate scenes. The Senate chamber had been faithfully recreated on the Columbia stages by art director Lionel Banks and a huge team of craftsmen, and the set was just that: a chamber. It was a tall, four-sided set filled with hundreds of people. Action required for the story would also be taking place simultaneously on three levels: the Senate floor, the rostrum where the Vice President sat, and the galleries holding the press, the pages, and the public. As Capra put it in his autobiography, "How to light, photograph, and record hundreds of scenes on three levels of a deep well, open only at the top, were the logistic nightmares that faced electricians, cameramen, and soundmen."
James Stewart was delighted with his role, and began to attend the rushes--something he had seldom done with his films at MGM. Frank Capra screened the footage at the projection room in his house. Stewart said, "The first time I stopped off at Capra's house I was there an hour and forty minutes. There was take after take, from every angle. He really covered himself. Every scene from every angle. Well, I didn't stay to the end. The next night it was clearly going to be even longer! After an hour I turned to Frank. He was fast asleep." Needless to say, Stewart soon went back to avoiding dailies.
Edmund Mortimer was first chosen for the role of Sen. Agnew, and studio records/casting call lists reflected this. However, Mortimer dropped out of the finished film entirely, and the role went to H.B. Warner.
Frank Capra would also rely heavily on reaction shots of the many observers in the scenes set in the Senate chamber. He wanted to retain a natural flow to these shots and so, for these reasons, the usual one-camera set up could not be employed; "...we might still be there," Capra said. The technical team "...devised a multiple-camera, multiple-sound method of shooting which enabled us, in one big equipment move, to film as many as a half-dozen separate scenes before we made another big move."
Before the film was released to the general public, a major screening was held in Washington, DC, at the invitation of the Washington Press Club, at Constitution Hall on October 16, 1939. More than 4,000 people attended, including senators, congressmen, Supreme Court justices and much of the Georgetown elite. Harry Cohn was there, and Frank Capra and his wife attended, sitting with the family of Sen. Burton K. Wheeler, Republican from Montana (although Montana was never mentioned as the state Jefferson Smith was from in the film). Some biographers have charged that Capra "overdramatized" his account of the preview in his book, and that there wasn't a flood of walkouts as he wrote. The audience was only superficially polite at best, however, and there were certainly strong reactions from certain congressmen and members of the press in the days and weeks that followed.
Joseph P. Kennedy, the ambassador to Great Britain, sent Harry Cohn a cablegram urging him to withdraw the film from European distribution. Kennedy wrote, "I have a high regard for Mr. Capra ...but his fine work makes the indictment of our government all the more damning to foreign audiences... I feel that to show this film in foreign countries will do inestimable harm to American prestige all over the world. ...Pictures from the United States are the greatest influence on foreign public opinion of the American mode of life. The times are precarious, the future is dark at best. We must be more careful." Cohn and Frank Capra had sent Kennedy many clippings from American reviews and editorials, all praising the film and expressing the opinion that Democracy can withstand, and in fact encourages, such questions as the film raises.
Harry Carey's role is credited as "President of the Senate". He is presumably also the Vice-president of the United States. However, in those days, if the Vice-president died in office, he was not replaced until the next presidential election, so the job of President of the Senate would devolve upon a senator designated as the President Pro Tem of the Senate. The movie does not say which the President of the Senate is.
H.B. Warner and Pierre Watkin's characters are, respectively, credited as Senate Majority Leader and Senate Minority Leader. In the script they also have names, respectively, Sen. Martin Agnew and Sen. John Barnes. Their party affiliations are presumably opposite, but it is never stated which is a Democrat and which a Republican.
Although the plan in Senator Smith's (James Stewart) Senate Bill called for the creation of a National Boys Camp was a truly unusual proposal for that or any day, its plan of financing may have been a stumbling block itself. The reason is that the Laws governing Congressional authority states that all Revenue Bills must originate in the House of Representatives and not in the Senate.
The trivia items below may give away important plot points.
Originally the ending was much, much longer. It included scenes such as Mr. Smith going back to his home state and given a parade (with Saunders); the Taylor machine being crushed; Smith on a motorcycle and stopping to see Sen. Paine; forgiving him and everyone going to see Smith's mother. It was cut after a preview audience's response. Some of the footage can be seen in the theatrical trailer.
During Smith's filibuster, he mostly sticks to improvisation and reading from historical documents (The Declaration of Independence, The Constitution, etc). However, during one scene (immediately following the montage of the dueling newspapers), he reads from the King James Bible, specifically the "love passage" in 1 Corinthians 13.
The ending of the film was severely cut following previews. Originally, there was a protracted denouncement. Following Smith's collapse on the Senate floor, there were several scenes showing his triumphant return to his home state. He and Saunders are given a parade, the political machine of James Taylor is dismantled, Smith visits Senator Paine at home and forgives him, and there is a reunion with Ma Smith and her blessing given to Saunders as a daughter-in-law. Two brief shots of parades are seen in the trailer.
