Destiny of the Daleks - S17-E1

Revealing mistake: In episode one, when the Doctor and his companion hear rumbling and the ground moves beneath their feet, when they step away you can see that they are standing on different ground than before, and it's not shaking. (00:08:00)

Destiny of the Daleks - S17-E1

Deliberate mistake: The shot of the alien spacecraft flying in the sky is the same in episode 4 as in episode 1, only it's reversed. The taking off and landing are the same too, except smoke and rubble have been added.

Destiny of the Daleks - S17-E1

Revealing mistake: When the Doctor and his companion are running past explosions in the sand, you can see the scrape marks from where the effects team covered up the holes containing the charges. (00:13:00)

The Caves of Androzani - S21-E6

Continuity mistake: When the Doctor and Peri first land on Androzani, mountains are seen in the background. They disappear when Peri picks up the silica. A couple of shots later, they're back. (This mistake was mentioned on the DVD commentary; the mountain effect was left out for financial reasons).

The Caves of Androzani - S21-E6

Revealing mistake: It's already been mentioned that Peri bounces off a mattress, but watch what happens when the Doctor walks over to see if she's all right. The 'cave' floor visibly moves under his foot.

Visible crew/equipment: The boom mike is visible at the top of the screen when one of Jek's androids is handing spectrox to the mercenaries. The shadow of the boom pole is also visible on the roof beam.

Trivia: On the DVD commentary, Peter Davison remarks that when Christopher Gable whacked him across the face with the back of his hand, it actually hurt quite a bit, even though they'd discussed it beforehand. Davison believes that Gable couldn't see him properly with his mask on, although a more likely explanation is that Gable got too carried away.

The Caves of Androzani - S21-E6

Factual error: Sharaz Jek's monitor that displays the tunnels and his androids is inaccurate. The white blobs are, as we learn later, supposed to represent his androids. He tells the Doctor that the green area is held by the army, yet on the screen the green area is populated by androids, so they could not have had control.

The Caves of Androzani - S21-E6

Revealing mistake: When Stotz cuts a hole in his ship's door, you can see that the inside of it is made of white polystyrene. They painted the outside of it but obviously forgot about the inside. Also listen to the sound it makes when Stotz punches the hole through - it sounds exactly like polystyrene.

The Caves of Androzani - S21-E6

Factual error: When the Doctor is trying to land the ship, from the video screen it appears that they are moving towards the planet way too fast to make such a safe and quick landing. Also, the ship doesn't seem to have even penetrated the planet's atmosphere yet it lands seconds later.

Earthshock - S19-E6

Continuity mistake: The hole that the Cybermen make in the door increases in size just before they step through it. (01:09:10)
