Visible crew/equipment: After MacReady says, "The generator room," toward the end of the film, he, Garry and Nauls walk down a flight of stairs. Then Garry and Nauls walk down a set of three steps whilst Mac is holding a flare. As they walk the shadow of a guy holding a boom mic is clearly visible on the floor.
Visible crew/equipment: When Windows is in the radio room, he is trying to communicate with McMurdo. Doctor Blair then enters the radio room and approaches him, tapping his shoulder. Windows then pulls his headphones down from his ears and has them placed around his neck and he then says to Doctor Blair, "Nobody." Just as he says this, there are two white screens visible in his glasses.
Visible crew/equipment: Bennings tells Nauls to turn down the Superstitious song and Nauls skates over to the radio, but then doesn't turn the radio down at all. The shot then cuts to a shot of the medicine room which then continues as a panning shot and pans into the next room. Just as the camera stops panning and the shot remains still, there are a few stage lights visible reflected in one of the cabinets on the right hand side of shot. Those certainly aren't lights because all of the lights in the room are switched off.
Visible crew/equipment: Just after Nauls is told by Bennings to turn down the music the film cuts to a tracking shot going towards the rec hall. At the very beginning of this tracking shot keep an eye on the lower half of the medical cabinet, and you can easily see the dolly that the camera is being pushed on. If you look just above the dolly you can make out the blue sweater sleeve of the crewmember pushing it as well.
