Visible crew/equipment: When they capture the brain bug, just before Carl says "It was a man called Zim [who captured the bug]", you can see a microphone antenna shadow is visible on his back. The shadow of the camera on his shoulder can also be seen in the fullscreen DVD edition. (01:57:35)
Visible crew/equipment: In the scene towards the end, in the cavern containing the brain bug, there's a pyrotechnic set-piece of a massive quantity of ammo being used up. This was filmed from a number of angles, and in one shot, looking down across the cavern there is a camera man and an assistant visible in the mouth of one of the tunnels leading in. I don't know if this is corrected in the DVD release, but it was certainly there in the UK theatrical version.
