Continuity mistake: When Hoskins is talking to Owen at the raptor paddock, Barry crosses the gate in one shot, but when the angle changes, Barry crosses the gate again. (00:23:20)
Audio problem: When they are standing at the top of the waterfall Owen talks to Clare from behind and his mouth isn't moving. (01:06:10)
Continuity mistake: After Claire shoots the Dimorphodon the sun changes between shots. (01:22:30)
Continuity mistake: When the guy scrambles out of the raptor paddock the distance between him and the fence behind him varies between shots from close to far away. (00:24:00)
Factual error: In the airport scene, this is not Dane County Airport as shown, as they do not use letters for their gates (A, B and C shown). They use numbers (1-13) instead. (00:03:10)
Other mistake: When the I-Rex finds Owen and Clare at the visitor center garage, Owen's gun is leaning up against the JP jeep. The I-Rex knocks up the jeep, but the gun doesn't fall over.
Continuity mistake: The restricted zone where the original Jurassic Park was is to the north. After Indominus chases the kids to the waterfall, it is said in the control room that the huge dino is moving south to the crowds waiting for rides to reopen in the downtown section, drawn by the heat signatures of the gathered masses. A few scenes later, Indominus is up north again terrorizing the kids at the Jurassic Park jeep port.
Continuity mistake: When Zack's brother is crying about thinking their parents are going to get divorced, behind Zack it looks like the background loops in every shot of him.
Visible crew/equipment: When Masrani puts his sunglasses on you can make out a camera reflection in the glass. (00:15:10)
Continuity mistake: When Claire gets into the helicopter at the start her microphone is level with her mouth. As it takes off, it's pushed down by her shoulder. (00:13:50)
Continuity mistake: When Masrani is driving the chopper for first time, the wire on his headphones is in front of the mic, then behind it. (00:13:30)
Continuity mistake: When Barry helps Owen get up off the ground, when the camera changes, the shadow of cage bars appear out of nowhere on Barry's back.
Continuity mistake: When Hoskins is talking to Owen, he touches his back with his right hand. When the camera changes, he is using his left hand. (00:14:05)
Continuity mistake: During the first appearance of helicopter JW001, as the helicopter turns to the right to align with the helipad, the entrance door to the helipad is closed. In the next shot, the door is open with Claire standing there, waiting for the touchdown. (00:13:00)
Suggested correction: The chopper is also considerably closer after the cut indicating a time skip of a few seconds. Plenty of time to open a door.
Continuity mistake: When Clare walks into the control room, no part of the park is closed. But, when she asks about the west plains, they appear closed. There would not have been time to catch the Pachycephalsarus. (00:11:00)
Continuity mistake: When Indominous Rex has the gyrosphere in its mouth and is smashing it, the seats are facing up. When the passengers release their safety belts and fall to the ground, they are facing down. (00:59:20)
Continuity mistake: When the movie begins, a group of kids are watching a documentary. The employee holding the iPad lowers his right arm, then it's raised again in the following shot.
Visible crew/equipment: When Claire and the soldiers are running to shoot the birds, a camera shadow can be seen on her briefly. (01:22:00)
Continuity mistake: When running towards the Pteradons, Claire is with a group of ACU units. Camera changes and she's not in shot. In the reverse angle, she does run to the side, but even from the front angle she should have been visible. (01:22:00)
Other mistake: When Claire is running to the quad bike she gets a phone call and answers it. However, 1) the phone doesn't light up or show any indication it's ringing and 2) she doesn't press anything but somehow answers the call. (01:19:00)
