Final answer:
Non-diegetic content in films includes elements like the score, voice-over narration, and other components that do not exist within the story's environment. Diegetic elements, however, are part of the story's world. The film Babel uses both to enhance storytelling and introduce cross-cultural themes.
Step-by-step explanation:
A term used to denote material within a film that comes from outside the world of the story is called non-diegetic content. This can include elements like the film's score, voice-over narration, and other components not physically present within the story's environment or experienced by the characters. For example, a third-person omniscient or limited narration is a non-diegetic element, as it is a voice that comes from outside the story and can provide the audience with information about the characters and events. Additionally, physical elements such as costume changes to depict a character's altered state or lighting cues that transport the actors and audience into a new setting, while part of the film's aesthetic, are considered diegetic, as they exist within the story's world.
