Visible crew/equipment: After the demonstration at the blackboard, the big group of soldiers walk over to the big table with the picture of the world on it. As they walk away from the blackboard, they turn and walk down some steps, and as they do you can see the shadow of a boom mic pole on the upper side of the grey part of the wall. (00:55:40)
Visible crew/equipment: Opening credits (also a few minutes in) has a fiery spaceship crashing into the camera for this was a 3D movie. What's interesting is that a mirror can be seen on the left portion of the screen just before the collision. This was apparent at the theatres and on the VHS tape release. For some reason, the DVD release has it cropped out and now the spaceship is off-centered at the beginning (fortunately the bonus material still shows it). (00:00:20 - 00:03:50)
Visible crew/equipment: George Loomis talks to Polly in the boat and looking outside the window it's easy to see that there's no island in front of them. A few shots later it's obvious that the island is superimposed on the falls. (01:21:15)
