Plot holes are inexplicable contradictions in literature and film. They usually entail some sort of logical fallacy in either the author's narration or in the decisions made by a character.
Often in fiction, a willing suspense of disbelief may be required to appreciate the story, which can allow the audience to overlook minor discrepancies. However, depending on how scrupulous the reader or viewer is, and depending on the size of the plot hole, such errors can detract from the story.
In "The Lord of the Rings," Frodo and Sam are rescued by giant eagles from deep within enemy territory in Mordor after destroying the One Ring. It is often pointed out that the eagles could have simply flown them in as well, instead of having the hobbits walk for hundreds of pages to Mount Doom.
In the animated film "Toy Story," the new toy Buzz Lightyear hilariously does not believe he is a toy when he first arrives at Andy's house. However, he always complies with the "Andy's coming!" routine where all the toys always freeze when a human enters the room, and in this sense, acts exactly like a toy.
In the original film and remake of "King Kong," the giant primate is kept at bay on his island by a wall constructed by the native people. Famously at the end of the movie though, Kong climbs the much higher Empire State Building in New York City.
In "Star Wars," Luke keeps his father's original last name of Skywalker. Yet, few characters in the galaxy seem to make any connection to his infamous father. Critics have also wondered how Princess Leia came to have the title of "princess" if her true identity was hidden.
