Audio problem: When Cutter rolls and shoots at Vincent, we can hear the distinct sound of his pistol. However, we see a shot of the pistol's slide in the open/locked position, meaning he's run out of ammo, but we can still hear the pistol being fired a few times after that.
Passenger 57 (1992)
1 audio problem
Directed by: Kevin Hooks
Starring: Wesley Snipes, Tom Sizemore, Bruce Payne, Alex Datcher
Revealing mistake: When the terrorists drop the dead body out the aircraft door, look closely at the aeroplane just beneath the door, you can see the reflection of the mat the stuntman lands on, as well as the spotters around it.
John Cutter: Now I'm sick of your shit.
Charles Rane: You need the passengers, I need the plane. Put me back on board and the passengers will be released.
John Cutter: Yeah right. I'm supposed to trust you?
Charles Rane: Trust your instincts.
John Cutter: My instincts are to wax your ass all over this floor.
Charles Rane: Those are your emotions acting without the benefit of intellect.
Trivia: At the fairground, when Rane and the two terrorists walk away as Cutter is arriving, there's a white Honda Civic seen. It's license plate reads "outatime", the same as the plate on the DeLorean in Back to the Future.
Question: How did the FBI agent know that the two FBI agents on the plane were killed earlier?
Answer: It's been a while since I've watched this movie, but he obviously knows the plane is hijacked. It's a pretty safe assumption that the agents are dead as they're escorting a dangerous, high profile prisoner. Pretty easy to connect the dots. Alternatively, they could've failed to check in, and he assumed the worst.
Answer: When ground crew, first responders, and police are near the plane, you can see paramedics stacking body bags in an ambulance. It's safe to assume the bodies were dumped after Captain Whitehurst was dumped from the plane.
