Revealing mistake: A skeleton of early man is found by a workman digging through mud at an extension to the Underground railway system in London. The skeleton is suspended in a pocket of air, however, and shows no mud inside the rib cage or other body cavities.

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.

Continuity mistake: A borazon drill was used to cut a hole into a panel. The hole was rather large, but when the special effects began showing the panel dissolving, the hole was much smaller.

Revealing mistake: The flashlight that the drillman used when the lights went out around the spaceship didn't match the light from the spot used by the film crew.

Continuity mistake: Quatermass used tweezers to pull away the membrane covering the eye of a dead martian. A scene later, the membrane was intact.

Visible crew/equipment: As the drillman was removing his equipment from within the spacecraft, the gravity became nonexistent and all the tools began to float. You can easily see wires on all the tools - especially the flashlight.

Revealing mistake: After the spaceship becomes alive and causes a cave-in, Barbara easily stumbles and moves the large chunks of broken cement beams as she leaves the pit with Quatermass.

Continuity mistake: The martians that were pulled out of the spaceship had compound eyes much like a fly. However, the lifeforce of the martian over London, had cross-eyed pupils.
