The 1931 Charlie Chaplin film in which the Tramp falls in love with a blind flower girl is City Lights.
Chaplin plays the Little Tramp, who meets a blind flower seller played by Virginia Cherrill. Because she mistakes the sound of a car door for the arrival of a wealthy customer, she initially believes the Tramp is rich. He later becomes involved with an eccentric millionaire and tries to raise money for the flower girl's sight-restoring operation.
City Lights was made after sound films had become dominant, but Chaplin chose to avoid spoken dialogue. It uses synchronized music and sound effects, English intertitles, and a score composed by Chaplin. The film's emotional climax depends on the flower girl finally recognizing the Tramp by touch after her sight has been restored.
A common misconception is that City Lights is completely silent in the technical sense. It has no spoken dialogue, but it is a synchronized sound-era production. Chaplin also used José Padilla's song “La Violetera” as a recurring musical theme, later losing a lawsuit over its uncredited use.
