Cat's Eye (1985)

Factual error: When Cressner falls and lands on the horn, it makes the same pronounced honk sound as when he had honked it at Norris. In reality this wouldn't be possible because the bell of the horn was compressed on landing when Cressner threw it out the window earlier, so the sound would've been higher pitched, if it was still able to make a noise at all.

Sally Ann: Polly got in one good peck before that cat killed her. Good for Polly.
Hugh: I certainly never realised that Polly had such a big pecker.

Trivia: This was the first theatrically released Stephen King movie to get a PG-13 rating instead of an R.
