I remember reading an article about Citizen Kane and the author of the article said that the shot of the bridge before seeing Leland didn't make sense. The bridge shot made sense to me because I took it as visually telling the audience that Leland was Kane's bridge to the working man. The shots that stick in my mind is the marriage montage at the table, the roof top shot through the building sign, the snow and handwriting dissolve, and Kane dancing on the city.
25: Kane in newsroom with his two friends and Thatcher. Kane gives the line about "I'll provide the war." Kane intensifies the turbulence when he talks about his stock holdings and his passion for protecting the underprivileged as publisher of the Inquirer. This begins Kane's mission to help the less fortunate. The birth of something new.
45: Leland and Bernstein in a room full of statues talking about Kane getting the world's biggest diamond for his new romance. In the next scene Kane accepts a trophy and announces his engagement. Now that I'm aware.
60: Kane is with Susan as she sings at the piano. Kane applauds and applause connects us to the next scene with Leland talking to a group of people about Kane helping the working man. The next scene is Kane speaking about dishonesty to a large audience with many signs and a big image of Kane. We soon learn that Kane's wife will discover Kane's betrayal and this revelation will cost Kane the election. There's no going back now.
-45: In the newsroom with Kane after the election loss, Bernstein exits. Leland enters, drunk. They talk about how Kane's flaw has set back the cause of reform. Leland talks about the people and their rights not belonging to Kane. Discovery.
-25: Susan is on stage at the start of a large production and she sings poorly. Kane and Susan withdraw from the public eye and eventually she leaves him and he dies. The final turning point.
