Final answer:
If we speak of an element of a given film as being nondiegetic, it means that it is not shown onscreen. This statement is true.
Step-by-step explanation:
If we speak of an element of a given film as being nondiegetic, it means that it is not shown onscreen. This concept is related to how elements such as background music, voiceovers, or flashbacks are used in a film to provide additional information or context for the story but are not part of the immediate narrative. For example, if there is a scene in a film where a character is thinking but their thoughts are conveyed through voiceover, the voiceover would be considered a nondiegetic element because it is not heard by the characters within the film.
Therefore, the statement is True. If an element is nondiegetic, it is not shown onscreen.
