Visible crew/equipment: As Quatermass drives back to the spaceship in a cab, just before it is to be drilled, the film crew can be easily seen in the cab's windows. A woman with a white cap can be seen holding a script. Later when the police use a megaphone on their car to announce the spaceship is a hoax, you can again see the same woman with a white cap in one of the windows of the police car.
Suggested correction: How could you tell if the reflection showed the actual film crew and not just a TV and newsreel crew assembled for the scene? They were also using mounted cameras and carrying papers.
Visible crew/equipment: The very last scene, something swings in and out of the frame, on the right, just as Quartermass is rounding the corner.
Suggested correction: After viewing the scene frame by frame, it is clear that something grey and textured enters the edge of the shot from behind the wall for a few frames, but it is not identifiable. Given the turbulence of the disaster setting it could as easily be identified as a flapping wall poster or a piece of torn curtain as set crew or equipment.
I have studied the image frame by frame and you can see it is a right hand of someone, possibly a crew member not getting out of shot quick enough. The strange thing is that the hand is dark and hairy almost werewolf like. Obviously not a werewolf but maybe someone in makeup from another Hammer movie was visiting the set.
After examining the still frame, the object is definitely an arm and hand. It may appear distorted because it is much closer than the focal point and near the edge of view of what looks like a Panaflex camera lens. Lighting, poor focus, and lens effects could have made a crew member's wool sweater look like a furry arm and elongated his fingers.
