Tramp's friend when drunk but does not recognize him when sober. Chaplin officially began pre-production of the film in May 1928 and hired Australian art director Henry Clive to design the sets that summer. Chaplin eventually cast Clive in the role of the millionaire. Although the film was originally set in Paris, the art direction is inspired by a mix of several cities. Robert Sherwood said that "it is a weird city, with confusing resemblances to London, Los Angeles, Naples, Paris, Tangiers and Council Bluffs. It is no city on earth and it is all cities." On August 28, 1928, Chaplin's mother Hannah Chaplin died at the age of 63. Chaplin was distraught for several weeks and pre-production did not resume until mid fall of 1928. Psychologist Stephen Weissman has hypothesized that City Lights is highly autobiographical, with the blind girl representing Chaplin's mother, while the drunken millionaire represents Chaplin's father. Weissman also compared many of the film's sets with locations from Chaplin's real childhood, such as the statue in the opening scene resembling St. Mark's Church on Kennington Park Road and Chaplin referring to the waterfront set as the Thames Embankment. Chaplin had interviewed several actresses to play the blind flower girl but was unimpressed with them all. While seeing a film shoot with bathing women in a Santa Monica beach, he found a casual acquaintance, Virginia Cherrill. Cherrill waved and asked if she would ever get the chance to work with him. After a series of poor auditions from other actresses, Chaplin eventually invited her to do a screen test. She was the first actress to subtly and convincingly act blind on camera due to her near-sightedness, and Cherrill signed a contract on November 1, 1928. Principal photography Filming for City Lights officially began on December 27, 1928, after Chaplin and Carr had worked on the script for almost an entire year. On the set, Chaplin was noted for doing many more "takes" than other directors at the time. Production began with the first scene at the flower stand where the Little Tramp first meets the Blind Flower Girl. The scene took weeks to shoot, and Chaplin first began to have second thoughts about casting Cherrill. Years later, Cherrill said, "I never liked Charlie and he never liked me." In his autobiography, Chaplin took responsibility for his on-set tensions with Cherrill, blaming the stress of making the film
