Blow Out (1981) John Travolta, Nancy Allen, John Lithgow – Arrow Video (Begagnad)

Former police technician Jack Terry makes his living doing sound for slasher flicks. While recording new outdoor effects one night, Jack witnesses a couple's car careen off a bridge into a river, but he can save only the female occupant, Sally. Jack begins to suspect something when he learns that her dead companion was a presidential hopeful. Re-playing his tape over and over, Jack thinks that he hears a gun shot before the crash-causing tire blowout. When sleazy photographer Manny Karp comes forward with photos of the accident, Jack discovers the real reason that the naïve Sally was in the car—and also a way to prove his auditory suspicions through motion pictures. Even with all his surveillance talent, however, Jack cannot see (or hear) how dangerous the big picture really is until it's too late.
