Survival: | ||
 | ep 1 – | The reflection of a large grey boom microphone is visible in the glass panel next to the door as the Doctor and Patterson leave the youth club. |
 | ep 2 – | When Ace watches Karra approaching the lake, look out for the electricity lines in the background of the (supposedly primitive) Cheetah Planet. |
| ep 2 – | The Master captures Midge with a lasso trap around his feet, but we never see him untie Midge's legs before the two of them teleport away (even though the action is supposedly continuous between the two events). |
| ep 2,3 – | Also when Midge is captured, the sabre-tooth he's carrying gets knocked to the ground. Neither he nor the Master pick it up before they teleport to Earth. Yet in Part 3, the Master is able to present it to Midge as he's about to ride his motorbike towards the Doctor. |
| ep 3 – | The motorbike collision stunt is totally ridiculous; the director shows the collision in a wide long shot, with a tremendous explosion and fireball engulfing the two bikes. Yet subsequent shots show that both riders were supposedly thrown clear — the Doctor completely unmarked, and Midge with just a few soot marks on his face! Unbelievable. |
