The Rescue: | ||
ep 1 – | When the travellers are entering and leaving the TARDIS in the cave scenes, it's obvious that the police box shell has no back to it — the cave wall can be seen through the doors! | |
ep 1,2 – | Koquillion wears clawed feet in episode 2, but not in episode 1 (see, for example, the scene where he enters the spacecraft to confront Vicki). | |
ep 2 – | When Sandy (Vicki's "pet") is seen in its cave just before Barbara kills it, a stagehand is visible moving around behind it to the left. |
