In conjunction with the release of this film (c. 1968-1969), Random House published a hardcover novelization of the film's screenplay for younger audiences, illustrated with stills from the film. Among the stills featured were scenes showing the arrival at the workhouse and the death of Oliver's mother, who, at least in U.S. prints, never appears in the film.
Early rumors regarding casting included Richard Burton and Elizabeth Taylor as Bill and Nancy, and either Laurence Harvey or Peter Sellers as Fagin; though eventually Ron Moody was asked to reprise his stage role. Jack Wild had played one of Fagin's boys in the London production, but was now old enough to play the Artful Dodger. Shani Wallis finally won the role of Nancy nearly a year after first auditioning when she demonstrated an acceptable Cockney accent - the one she grew up with.
The London sets covered six sound stages and a huge studio backlot - with rich and poor sections. The sets were adaptable overnight in spite of their sturdy look, due to the fact that single dance numbers sometimes required changing sets up to a dozen times.
"Boy For Sale" was shot in July despite the required snow setting; exterior shots depended on adequate cloud cover due to the erratic weather in London. The snowballs were made of polystyrene, salt, crazy foam and mashed potatoes.
The cast included 84 boys between 8 and 15 years of age, and one member of Parliament suggested they were being exploited just as the depicted orphans had been. The filmmakers replied that they needed protection more than the boys did, due to the rowdy nature of the production during the summer.
Amazingly, the composer of this highly respected score, Lionel Bart, could not read music himself. From his earliest days in theater, he would sing his melodies to a trained pianist, who would then set the tunes down on sheet music and orchestrate them.
While filming the scene where Oliver gets a peek at Fagin's treasure, director Carol Reed was not satisfied with the reaction on Mark Lester's face. Later, while re-shooting the scene, he hid a small white rabbit in his pocket and stood behind the camera. As Ron Moody opened the box of treasures, Reed pulled the rabbit out of his pocket. Lester's reaction to the sight of the rabbit was then used in the final film.
Mark Lester did not do his own singing in Oliver! It was dubbed by Kathe Green, daughter of Johnny Green, the music arranger/supervisor on the film. Johnny revealed this for the first time publicly in 1988 during an interview on the 20th anniversary of the film. He says that Mark Lester was "tone deaf and arrhythmic". He originally had two boys set to dub his singing but during post production they realized their voices didn't match Mark's look, so they used Johnny's daughter instead.
The Magistrate that Hugh Griffith plays in the film did not appear in the original stage production of "Oliver!" He does appear in Dickens's original novel, "Oliver Twist", on which the musical is based. In the novel the Magistrate is named Mr. Fang, and although Dickens wrote him satirically, he did not intend him to be comical.
The original Broadway production of "Oliver!" opened at the Imperial Theater on January 6, 1963, ran for 774 performances and was nominated for the 1963 Tony Award for the Best Musical and received nominations for Best Book and Best Score.
As of 2007, this is the last G-rated film to win the Best Picture Academy Award.
In the original Broadway production, the Artful Dodger was played by future Monkee Davy Jones who was also nominated for a 1963 Tony Award for Best Featured Actor in a Musical for his performance.
Although Ron Moody had played Fagin to great acclaim on the London stage, he was only allowed to repeat his performance in the film after Peter Sellers and Peter O'Toole had reportedly turned down the role.
Oliver Reed's only song was cut from the finished film, officially because the producers decided that Bill Sikes should not sing, but also allegedly because there was concern over the quality of Reed's singing voice.
SPOLIER: Bill Sikes' death scene was taken directly from Sir David Lean's Oliver Twist (1948). Apparently Lean was not pleased about his friend Sir Carol Reed borrowing from his film without acknowledging him in the opening credits.
Ron Moody recalled that he did not know for certain until the first day of filming whether he had been cast or not.
Both Jack Wild and Oliver Reed were wearing lifts in the film. Although Wild was 15 at the time of filming, he was actually shorter than nine-year-old Mark Lester.
Approximately 5,000 boys were auditioned for the title role before Mark Lester was cast.
The only G-rated film to be honored with an Academy Award for Best Picture.
It was also the last musical to win the Best Picture Oscar until Chicago 34 years later.
The first film with an MPAA rating to win an Academy Award for Best Picture.
