A hint that is designed to mislead the audience is referred to as a red herring. A similar device is the flashforward (also known as prolepsis). However, foreshadowing only hints at a possible outcome within the confinement of a narrative. A flashforward is a scene that takes the narrative forward in time from the current point of the story in literature, film, television, and other media. Foreshadowing is sometimes employed through characters explicitly predicting the future.
In the novel and subsequent screen adaptation of The Lord of the Rings, Frodo considers it unfortunate that Bilbo pitied Gollum and was unable to kill him, but Gandalf feels that Gollum "has some part to play yet, for good or ill, before the end". This conversation foreshadows the fact that later in the story Frodo himself pities Gollum and is unable to kill him. Gollum then inadvertently makes it possible to destroy the Ring, which is the whole point of Frodo's and the rest of the central characters' quest.
Foreshadowing is used in much of the works of John Steinbeck. In Of Mice and Men, Lennie accidentally kills a mouse, a dog and finally Curley's wife. This foreshadows his own death. When Carlson kills Candy's Dog, Candy tells George, "I ought to of shot that dog myself" making George later chose to kill Lennie himself to save him from dying by the hands of a stranger. Doing it the way that Carlson did it was for the best because, "He won't even feel it."
