Foreshadowing is a narrative technique used to provide clues and hints for future events or developments in the plot. It involves presenting information, elements, or details early in the story that anticipate or suggest what might happen later. This is done to create anticipation, build tension, and engage the audience in the film.

There are many ways in which a filmmaker can foreshadow their narrative; the most common techniques are the use of visual cues and dialogue. Character behavior, set and atmosphere, music, and sound also contribute to effective foreshadowing.

In the film ‘Jaws,’ glimpses of a shark’s fin create anticipation and build tension before the actual full-fledged appearance of the shark later in the film.

In ‘Psycho,’ Norman Bates’ behavior and the use of sound effects create an eerie feeling that something is not right, which later culminates in the infamous shower scene that confirms the audience’s apprehensions.

Similarly, in ‘The Shawshank Redemption,’ the character Brooks Hatlen’s expressions of fear about life outside prison foreshadow his tragic fate later in the film.

In ‘Back to the Future’ (1985), several small details and comments made early in the film foreshadow later events and plot twists, such as the mention of the clock tower and its significance later in the film.

In ‘Apocalypse Now,’ the apocalyptic atmosphere with chaos and bombings happening around establishes an unsettling mood for the film, increasing the audience’s anticipation and fear of the unknown.

In ‘Rosemary’s Baby,’ at the beginning of the movie, neighbor girl Terry shows Rosemary a locket containing a mysterious substance. Later Terry’s accidental death creates an eerie environment that keeps the audience alert to the impending danger.

In the movie, ‘Interstellar,’ an example of effective foreshadowing can be found in the use of music during scenes involving time dilation and cosmic phenomena. The powerful music amplifies the sense of wonder as the characters navigate through awe-inspiring cosmic landscapes.

An effective foreshadowing keeps the viewer engaged in the story, and when hints are later revealed or expectations are met, it provides a certain kind of satisfaction that influences their overall response to the movie.
