* ActorAllusion: Kane knows plenty of magic tricks that amuse Susan. Welles himself was an amateur magician.

* CopiouslyCreditedCreator: Co-written, directed, and starring Welles.
* CreatorBacklash: Welles wasn't that big on the film. He preferred some of his later work, like his adaptation of Kafka's ''The Trial''. In a 1960 interview, he said, "I'm ashamed of Rosebud. I think it's a rather tawdry device. It's the thing I like least in ''Kane''. It's kind of a dollar-book Freudian gag, you know. It doesn't stand up very well."
** Mild. Welles stated that his only regret was dragging Marion Davies through the mud; Davies was actually a great comedic actress and a warm person.
* CreatorKiller: The "Greatest Movie of All Time" was also the movie that killed Welles standing as a director in Hollywood. Prior to ''Citizen Kane'', Welles himself was very much a victim of the HollywoodHypeMachine and when the movie bombed at the box office, no studio would allow Welles complete creative control over any more of his films. Subsequent flops would serve as the death nail to his career.
* DyeingForYourArt: To simulate heavy drunkenness, Cotten stayed awake for 24 straight hours, resulting in some unscripted flubbery (that caused Welles to grin despite himself).
* EnforcedMethodActing: Poor Dorothy Comingore endured physical and mental abuse from Orson Welles and ended up a near wreck by the end.
* HeyItsThatGuy
** Agnes Moorehead, who appears as Kane's mother, became a longtime character actress who later starred as Endora on ''Series/{{Bewitched}}''.
** Ruth Warrick, Kane's first wife, later became famous to soap opera audiences as Phoebe Tyler on ''AllMyChildren'', a role she played for thirty-five years.
** The great leading man Alan Ladd appears briefly as an extra near the beginning of the film in the projection room and again smoking a pipe near the end.
* MagnumOpusDissonance: Orson Welles saw ''Film/ChimesAtMidnight'' as his masterpiece.
* MethodActing:
** To simulate being drunk, Joseph Cotten remained awake for 24 straight hours. You can see Welles break character and grin when Cotten flubs his line and says "dramatic crimiticism." Of course, it was a ThrowItIn moment.
** Welles himself let himself go during the famous room trashing sequence, even hurting himself badly bloodying his hands while doing it. After filming the scene, Welles breathed, "I felt it. I ''felt'' it."
* OldShame: The only thing Welles ''really'' regretted was his portrayal of the Marion Davies {{Expy}} Susan.
* OneSteveLimit: Averted. The film has characters named Jim Gettys and Jim Kane.
* StarMakingRole: ''Kane'' was a Star Making Role to some extent for most of the cast, since the bulk of them were members of Welles' Mercury Theater troupe and they were all making their film debuts together.
** Joseph Cotten went on to a long and very successful career as a leading man in Hollywood.
** BernardHerrmann, who had been a music composer for the Mercury Theater, went to Hollywood along with Welles and the actors, composed the music to ''Citizen Kane'' as his very first film score, and went on to become one of [[PsychoStrings the most successful]] [[Film/{{Vertigo}} film composers]] [[TaxiDriver in movie history]].
** Welles himself is an interesting aversion. He was a star since age 16, and became famous for his theatre and (cough) [[Radio/TheWarOfTheWorlds radio]], and had in fact made three films prior to this (a bizarre short in 1934, a 40-minute film that was intended to be part of a hybrid stage play/movie performance in 1938, and he narrated a version of Swiss Family Robinson a year before Kane came out), but the movie almost destroyed his career.
** Sadly averted for Dorothy Comingore, who delivered a powerful performance as Susan Alexander but saw her career derailed by [[{{Defictionalization}} alcoholism]] and poor decision-making even before it was permanently ended when she was put on the [[RedScare Hollywood blacklist]].
* ThrowItIn: Joseph Cotten stumbling over the word "criticism". It was a genuine flub, but fortunately both he and Welles stayed in character (albeit Welles grins) and Cotten follows up with a brilliant ad-lib "I AM drunk", so it stayed in the film as-is.
* WhatCouldHaveBeen
** Originally, the movie was going to be based on the life of Howard Hughes with Cotten in the lead. Eventually, Welles realized [[RealityIsUnrealistic nobody would believe most of the stuff Hughes had done]], so he decided to make Kane a media baron instead.
** Welles was originally going to make an adaptation of Joseph Conrad's ''Literature/HeartOfDarkness'' but the executives didn't believe they could possibly stretch a budget far enough to cover it, so he made [[TropesAreNotBad ''Kane'']] instead.
* WordOfDante: Sort of. People assume Marion Davies had a bad career, as her expy in the film shows. In fact, Marion Davies was widely considered [[ShowPeople a talented actress and comedienne]], independent of all the publicity Hearst arranged for her. Hearst did push Davies towards melodramatic leading-lady roles. Davies - along with many others - recognized that her real gift was for light comedy.
