Visible crew/equipment: During the battle against the dinosaur skeleton, you can see a SFX guy in one shot as the creature whips its head around. He is on the left edge of the screen, standing partially in the frame and visible for nearly a full second.
Continuity mistake: In the final scene in which a man is shot in the airport (part of this scene actually recurs throughout the movie), the psychiatrist woman leans over him to hold him as he dies. From one angle, he reaches up to her face and his hand is clean. In the next angle, his hand is covered in blood as he touches her face.
Factual error: When the porter first gets ready to shoot at the terrorists (after Ryback falls off the train) he goes through a series of verbal instructions to remind himself what to do. The very first thing he says is "safety off". The problem is that the gun he is using is a Glock pistol. Glocks use a device called a "safe-action trigger" but they don't have a manual safety that you turn on and off.
Visible crew/equipment: When Neil (De Niro) breaks into Van Zant's apartment and shoots him, watch as Van Zandt flies backward. You can see a wire running up through the bottom of his sweat pants.
Continuity mistake: When the Aunt flags down the cop car, the cop has his seat belt on, as the plant starts coming in the car to grab him and the car. He jumps out of the car without ever undoing his seat belt. (01:14:45)
Continuity mistake: In the last scene on the roof when Holly Hunter shoots the serial killer, he falls backwards. The gun is in his left hand and the path is next to his left hand. The camera then goes to the rear of Sigourney as she walks toward Holly. Only now the serial killer is on the other side of the path and the left hand holding the gun is no longer next to the path.
Continuity mistake: When the FBI meets them in a parking garage to pick up & protect Cindy Crawford as they are driving away, the partner in one car, Cindy & Baldwin in the other car the partner is shot in the head, creating a blood splatter on the window - however if you look carefully this blood splatter is already on the window when they show the car turning a corner in the garage - right before he is shot!
Plot hole: The group poison a dozen or so people and dispose of their bodies by burying them in their own garden. Some of their victims are notable celebrities - television presenters, authors, leaders of large and vocal pressure groups. Certainly some of them are nobodies, but nonetheless they are going to tell friends where they are going for dinner! Not one of these people told their assistants or their secretaries or a friend or a relative - a spouse? - where they were going and what they were doing on the night they were murdered? Not one of them? Not one single trace was left for the police to follow? Absolutely impossible.
Continuity mistake: When Selena is leaving on the ferry near the end, and Detective John Mackey pulls up and watches her drifting away, as he gets out of the car the windsheild wipers stop moving. In the next behind shot of him standing at the dock edge, watching, they are back on again. (01:43:05)
Revealing mistake: Brayker shoots The Collector through the eye with an arrow just after he's collected the key from Roach. You can see the section of the arrow shaft that sticks out the back of The Collector's head bend as his head hits the floor after he falls over the upstairs railing and crashes through the coffee table.
Continuity mistake: This is the car chase scene, where Ralph Fiennes and Angela Bassett are in a limo being chased by two bad cops in a pickup. Early in the scene, you have the view from inside the pickup when it rams the limo from the rear passenger side, and you can clearly see bullet holes in the glass and rear of the limo (no weapons fired yet). Then a few seconds later in the scene, you can see the rear of the limo with no damage. Moments later, you see one of the cops firing an automatic weapon, and subsequently witnessing the holes being made in the limo.
Continuity mistake: When J-Bone is coming down from Heaven, the lift he's on stops quite a way off the ground, and moves when he steps off it. Yet when he, Johnny and Jade step onto the lift, it seems to be on the ground as it doesn't move. It couldn't have been lowered, as we would've heard the noise of the motors.
