Citizen Kane
Style

Film scholars and historians view Citizen Kane as Welles's attempt to create a new style of filmmaking by studying various forms of it and combining them into one. However, Welles stated that his love for cinema began only when he started working on the film. When asked where he got the confidence as a first-time director to direct a film so radically different from contemporary cinema, he responded, "Ignorance, ignorance, sheer ignorance—you know there's no confidence to equal it. It's only when you know something about a profession, I think, that you're timid or careful."

David Bordwell wrote that "The best way to understand Citizen Kane is to stop worshipping it as a triumph of technique." Bordwell argues that the film did not invent any of its famous techniques such as deep focus cinematography, shots of the ceilings, chiaroscuro lighting and temporal jump-cuts, and that many of these stylistics had been used in German Expressionist films of the 1920s, such as The Cabinet of Dr. Caligari. But Bordwell asserts that the film did put them all together for the first time and perfected the medium in one single film. In a 1948 interview, D. W. Griffith said, "I loved Citizen Kane and particularly loved the ideas he took from me."

Arguments against the film's cinematic innovations were made as early as 1946 when French historian Georges Sadoul wrote, "The film is an encyclopedia of old techniques." He pointed out such examples as compositions that used both the foreground and the background in the films of Auguste and Louis Lumière, special effects used in the films of Georges Méliès, shots of the ceiling in Erich von Stroheim 's Greed and newsreel montages in the films of Dziga Vertov.

French film critic André Bazin defended the film, writing: "In this respect, the accusation of plagiarism could very well be extended to the film's use of panchromatic film or its exploitation of the properties of gelatinous silver halide." Bazin disagreed with Sadoul's comparison to Lumière's cinematography since Citizen Kane used more sophisticated lenses, but acknowledged that it had similarities to such previous works as The 49th Parallel and The Power and the Glory. Bazin stated that "even if Welles did not invent the cinematic devices employed in Citizen Kane, one should nevertheless credit him with the invention of their meaning." Bazin championed the techniques in the film for its depiction of heightened reality, but Bordwell believed that the film's use of special effects contradicted some of Bazin's theories.
