Plot hole: The main accident is a crash involving toxic waste, which seals the tunnel, yet no one has any trouble breathing, or even has so much as irritated eyes.
Daylight (1996)
1 plot hole
Directed by: Rob Cohen
Starring: Sylvester Stallone, Viggo Mortensen, Dan Hedaya, Amy Brenneman
Continuity mistake: In the same shot, note the top of the twin towers are in the clouds - its not a real nice day in NYC. But later when they're on the dock, there's not a cloud to be seen.
George Tyrell: Get them back to daylight.
