Continuity mistake: When Miles is talking with Sal for the first time, a cigarette suddenly appears on Sal's lips. (00:20:32 - 00:23:30)
Continuity mistake: When the bar collapses, the drunk guy's hat is raised but a shot later it's tucked down. (00:57:30)
Revealing mistake: When the highway collapses, the miniature prop is missing the delineators and lamp posts.
Visible crew/equipment: When the police chases the car, the camera is reflected on the siren.
Revealing mistake: During the jolt by the dam, the worker's table shakes, but not the rest of the stuff surrounding them, revealing that someone was moving the table underneath. (00:05:58)
Continuity mistake: After the quake, people rush down and find a man hanging onto a beam. Sam walks down towards him. Shot changes, and he is several meters behind, walking down again.
Continuity mistake: Miles is attempting to spin through a loop on his motorcycle. The first time he performs the stunt, he drives half way and falls out of the loop and lands on the ground. As soon as he and the bike land, the bike is positioned with the bike's wheels facing away from the loop. Miles is then helped up and the bike has suddenly shifted 180°, with the wheels now facing towards the loop.
Revealing mistake: Near the beginning, after a couple of small earthquakes, Fred comes flying out of the dam elevator shaft with a whole heap of water, dead from drowning. But you can see him lift his head out of the water seconds before his friend turns him over and finds him definitely dead.
Continuity mistake: After the bar where the drunk collapses, there's a scene of an office where a piece of ceiling falls on the left side. A second later, the office is clean and the ceiling falls again.
Other mistake: Early in the movie, at the dam when Fred is found drowned in the elevator, there was not enough water trapped in the elevator to drown him.
Other mistake: Outside of the office building, Stewart and Remy take shelter under a vehicle, despite falling debris crushing vehicles in their midst.
Visible crew/equipment: When Miles fails the stunt and falls, stage lights are reflected on his helmet. (00:47:21)
Character mistake: Remy is Sam's daughter despite that they look the same age.
Suggested correction: This would be trivia at best. Characters are often older or younger than the actors portraying them. Greene being less than 8 years older than Gardner in real life isn't a mistake.
