Visible crew/equipment: Beth attempts to convince Norman to inject himself with a tranquilizer by trapping him in a room and filling it with water. As the water rises, Norman frantically looks for a way out. There is a quick overhead shot of this scene that flashes on for just a second, and if you look around the perimeter of the room - you will see the entire crew, complete with camera and lights.

Mistakes
They're meant to be on rebreathers (they recycle the air around the system, so you 'rebreathe' it), yet in the u/w scenes, it can be seen that they're on open circuit systems, i.e. conventional scuba, as they're venting exhaust gases. Rebreathers do not release bubbles in the quantities shown. See more...

Sphere mistakes
Continuity: When Norman is running through the spaceship, he runs through a doorway and you get a glimpse of his facemask. It's dry. After going through water to get to the spaceship, wouldn't there be water on it?
Visible crew/equipment: When Norman gets back into the ship, Beth lies down with him for a few seconds. When the camera takes a shot from directly above the two, you can see a crewman's leg in the left side of the screen.
