Visible crew/equipment: When the rest of the cast try to revive Nelson at the end of the film, they try defibrillating him and check his vitals afterwards. There's one shot when the camera zooms into the screen of the heart rate monitor. In the screen reflection, a camera and camera operator are visible.
Flatliners (1990)
1 visible crew/equipment mistake
Directed by: Joel Schumacher
Starring: Julia Roberts, Kevin Bacon, Kiefer Sutherland, Oliver Platt, William Baldwin
Continuity mistake: Rachel's father kills himself after returning home from the Vietnam war (presumably in the early 70's) addicted to morphine. The problem with this is that he kills himself in a 1978 or '79 Ford pickup - Ford did not produce any pick-ups with square headlights until those years.
Nelson Wright: Somehow we've brought our sins back physically. And they're pissed.
Question: Just before Lebracio goes to the subway to find the ghost of Billy Mahoney, he crosses the street and about a dozen bicyclists come whizzing past him. Was this a hallucination? If so, why would he have a hallucination like that? If it wasn't a hallucination, what the heck are a bunch of racing bicyclists doing on a wet street that late at night?
Chosen answer: No hallucination. It was Halloween night, so everyone was acting a little crazy. That's why one of the med students shows up in a skeleton suit. Going further, the 'hum' of the bikes were used not only to throw the viewer off as the same humming noise Nelson describes with coming back from the dead, but to confuse Nelson with death and reality and these new sensations/feelings he is experiencing since being brought back to life. The cyclists are used, in a sense, to scare Nelson and viewers. The same 'hum' can be heard when Nelson first finds Billy Mahoney in the dingy tunnel.
