Imagery can be used in many metaphoric ways. In The Talented Mr. Ripley, the title character talked of wanting to close the door on himself sometime, and then, in the end, he did. Pathetic fallacy is also frequently used; rain to express a character feeling depressed, sunny days promote a feeling of happiness and calm. Imagery can be used to sway the emotions of the audience and to clue them in to what is happening.
Imagery is well defined in City of God. The opening image sequence sets the tone for the entire film. The film opens with the shimmer of a knife’s blade on a sharpening stone. A drink is being prepared, The knife’s blade shows again, juxtaposed is a shot of a chicken letting loose of its harness on its feet. All symbolising ‘The One that got away’. The film is about life in the favelas in Rio – sprinkled with violence and games and ambition.
Dialogue can be very important to the film industry, because there are no written words to explain the characters or plot; it all has to be explained through dialogue and imagery. Bollywood and other Indian film industries use separate dialogue writers in addition to the screenplay writers.
While the story is what will be told (narrative); the plot is how the story will be told (narration). This vocabulary is not indisputable for sometimes in literature stories and plots are used exactly the other way around.
