Lady for a Day is a 1933 American pre-Code comedy-drama film directed by Frank Capra. The screenplay by Robert Riskin is based on the 1929 short story "Madame La Gimp" by Damon Runyon. It was the first film for which Capra received an Academy Award nomination for Best Director and the first Columbia Pictures release to be nominated for Best Picture. Capra also directed its 1961 remake, Pocketful of Miracles.

The story focuses on Apple Annie, an aging and wretched fruit seller in New York City, whose daughter Louise has been raised in a Spanish convent since she was an infant. Louise has been led to believe her mother is a society matron named Mrs. E. Worthington Manville who lives at the Hotel Marberry. Annie discovers her charade is in danger of being uncovered when she learns Louise is sailing to New York with her fiancé Carlos and his father, Count Romero.

Among Annie's patrons are Dave the Dude, a gambling gangster who believes her apples bring him good luck, and his henchman Happy McGuire. Annie's friends from the street ask Dave to rent her an apartment at the Marberry and, although he initially declines, he has a change of heart and arranges for her to live in the lap of luxury in a palatial residence belonging to a friend. His girlfriend, nightclub owner Missouri Martin, helps transform Annie from a dowdy street peddler to an elegant dowager. Dave arranges for erudite pool hustler Henry D. Blake to pose as Annie's second husband, the dignified Judge Manville.

At the pier, an elegantly dressed Annie tearfully reunites with Louise. A group of Annie's friends from the streets are watching from a distance. One of the street people says that she can remember when Annie “always looked like that.” (We never know the details of Annie's history, but her upper-crust origins are clear.) When three society reporters become suspicious about Mrs. E. Worthington Manville, of whom they can find no public records, they are kidnapped by members of Dave's gang, and their prolonged disappearance leads the local newspapers to accuse the police department of incompetence.

A few days later, Blake – in the role of Judge Manville – announces he is planning a gala reception for Louise, Carlos, and Count Romero before they return to Spain, and he enlists Dave's guys and Missouri's dolls to pose as Annie's society friends. On the night of the reception, the police – certain Dave is responsible for the missing reporters – surround Missouri's club, where the gang has assembled for a final rehearsal. Dave calls Blake to advise him of their predicament, and Annie decides to confess everything to Count Romero. But fate – in the form of a sympathetic mayor and governor and their entourages – unexpectedly steps in and allows Annie to maintain her charade and keep Louise from learning the truth before she sails back to Spain with her husband-to-be.

Damon Runyon's short story Madame La Gimp was published in the October 1929 issue of Cosmopolitan. Columbia Pictures purchased the screen rights in September 1932, and the studio scheduled the production to begin the following May, although director Frank Capra had misgivings about the project. He reminded studio head Harry Cohn he was "spending three hundred thousand dollars on a picture in which the heroine is seventy years old," to which Cohn responded, "All I know is the thing's got a wallop. Go ahead." Robert Riskin was assigned to develop the story for the screen and wrote four drafts, submitting the last on May 6, 1933, three days before principal photography began. Aside from some minor revisions made during production, this final script was filmed intact. Riskin's version deviated from the original Runyon story primarily in that it linked its central character and a number of plot developments to the millions of Americans who were suffering as a result of the Great Depression. Runyon was pleased with the changes and later said, "Lady for a Day was no more my picture than Little Miss Marker, which, like the former picture, was almost entirely the result of the genius of the scenario writers and the director who worked on it."

Riskin had written his screenplay specifically for Robert Montgomery, but MGM refused to loan him to Columbia. He was among several performers Capra wanted but failed to secure for roles in the film. With Montgomery unavailable, Capra approached James Cagney and William Powell, but Warner Bros. refused to loan them out to work on this project. Capra's first choices for Apple Annie and Henry D. Blake, Marie Dressler and W.C. Fields, could not be cast for the same reason. The director finally cast his film with an assortment of character actors under contract (mostly from Warner Bros.) to Columbia. He also went to the Downtown Los Angeles neighborhood where he had sold newspapers as a boy and hired some of the street people who congregated there as extras who would add color to the film. One week before filming began, Capra offered the role of Apple Annie to 75-year-old May Robson, most of whose career had been spent performing on stage. In later years, Capra thought the fact she and most of the supporting players were unfamiliar to movie audiences helped the public accept them as the down-on-their-luck characters they were meant to be.

Just prior to the first preview in Hollywood in early July 1933, the film's title was changed from Madame La Gimp to Beggars' Holiday, then changed again before the film premiered at Radio City Music Hall on September 7. It went into general release on September 13 and within a very short time earned $600,000, twice its budget and a substantial sum for the period. According to the contract he had negotiated prior to making the film, Capra received 10% of the net profits. The film's success prompted the making of the 1934 film Lady by Choice, directed by David Burton and starring Carole Lombard. The only thing the two films have in common is Robson playing an alcoholic panhandler who has seen better days.^{[circular reference]}
