Sniper (1993) - 22 mistakes
starring Billy Zane, Tom Berenger
Factual error: In the opening sequence, the range for the shot is confirmed as 650 yards. Moments before the shot, AFTER he had his target centered in his scope, Berenger swings the muzzle of the rifle at least 10 degrees. At 650 yards a change of only a single degree in the angle of the muzzle to the target would mean that the target would have to move 11.34 yards laterally in order for the shot to hit. If Berenger actually had to swing his rifle ten degrees in the span of a second in order to keep his target in view, that would mean the target was sprinting at a speed of 340.32 feet per second, or about 232 miles per hour, and had covered 113.44 yards during that time. Absolutely impossible. Submitted by Mobrien316
Continuity: When Billy Zane is in the helicopter, he sights the sniper in his scope, the sniper being the one that just shot the chopper up. You see from the scope's view that the chopper is apparently following him running down the mountain. But, the helicopter was hovering, it wasn't following him.
