Brian De Palma’s famous 1981 thriller film Blow Out starts with a movie sound effects technician, Jack, who, while recording sounds for a low-budget slasher film in a wooded area near a river, serendipitously captures audio evidence of an assassination involving a presidential candidate. The candidate is sitting in a car that gets a blowout; the car slips into the water, and the candidate drowns. However, listening to the audiotape he inadvertently recorded of the accident, Jack distinctly hears a gunshot just before the blowout. What appears to be an accident caused by a flat tire turns out to be an attempted murder.
