The Beatles' First Film

Capitol Records' lack of interest throughout 1963 had not gone unnoticed, and a competitor, United Artists Records, encouraged United Artists' film division to offer The Beatles a motion picture contract in the hope that it would lead to a record deal. Directed by Richard Lester and originally released by United Artists, A Hard Day's Night was made in the style of a mock documentary, describing a couple of days in the lives of the group.
It was successful both financially and critically; it was rated by Time magazine as one of the all-time great 100 films. British critic Leslie Halliwell described it as a "comic fantasia with music; an enormous commercial success with the director trying every cinematic gag in the book" and awarded it a full four stars. The film is credited with having influenced 1960s spy films, The Monkees' television show and pop music videos.

The screenplay was written by Alun Owen, who was chosen because the Beatles were familiar with his play No Trams to Lime Street, and he had shown an aptitude for Liverpudlian dialogue. McCartney commented, "Alun hung around with us and was careful to try and put words in our mouths that he might've heard us speak, so I thought he did a very good script." Owen spent several days with the group, who told him their lives were like "a train and a room and a car and a room and a room and a room"; the character of Paul's grandfather refers to this in the dialogue. Owen wrote the script from the viewpoint that the Beatles had become prisoners of their own fame, their schedule of performances and studio work having become punishing.

The film was shot for United Artists using a cinema verite style in black-and-white and produced over a period of sixteen weeks. It had a low budget for its time of £200,000 ($500,000) and filming was finished in six weeks. Unlike most productions, it was filmed in near sequential order, as stated by Lennon in 1964. Filming began at Paddington Station on 2 March 1964, the Beatles having only joined the actors' union, Equity, that morning. The first week of filming was on a train travelling between London and Minehead. On 10 March, scenes with Ringo were shot at the Turk's Head pub in Twickenham, and over the following week various interior scenes were filmed at Twickenham Studios. From 23 to 30 March, filming moved to the Scala Theatre, and on 31 March, concert footage was shot there, although the group mimed to backing tracks. Among the 350 audience members was Phil Collins, who was a 13-year-old child actor at the time. The "Can't Buy Me Love" segment, which featured creative camera work and the band running and jumping around in a field was shot on 23 April 1964 at Thornbury Playing Fields, Isleworth, Middlesex. The final scene was filmed the following day in West Ealing, London, where Ringo obligingly drops his coat over puddles for a lady to step on, only to discover that the final puddle is actually a large hole in the road.
