Invasion of the Dinosaurs: | ||
 | ep 2 – | When the UNIT soldiers are shooting at the tyrannosaurus, the CSO is very badly lined up — making it seem like their rifles are aimed at the building beside it. |
 | ep 2 – | When the Doctor goes to inspect the stegosaurus, there's a blatant difference in the colour of the sky between the shots of the dinosaur (with the Doctor) and the shots of the Brigadier and his men (supposedly just behind the Doctor). This is made worse by the repeated switching between the two angles. |
| ep 2 – | When Mike Yates is about to sabotage the Doctor's gun, he glances down at it in the back of the Brigadier's jeep — and we can see that the sabotage device is already attached to the gun, although we don't see him put it on until shortly afterwards. |
| ep 3 – | In the shot of the Doctor driving the jeep, on his way to the hangar, his hair looks quite different to any other time in this episode.
[Looks like this was a shot left over from the chase sequence in episode 5 which the director found another use for...] |
| ep 3 – | When Sarah is hit on the head by a beam knocked loose by the dinosaur, it clearly hits the back of her head — but afterwards it's her forehead which appears bruised and scratched. |
| ep 4 – | In the first scene with the "Whomobile", just as the Brigadier is saying "Wouldn't you rather have a jeep?", a black baton or tube with a white tip passes from right to left across the bottom of the picture. It looks very much like the Doctor's portable detector we see a bit later, but it can't be Jon Pertwee who's waving it around — as the camera zooms out a bit we see his hands are down, inside the car. |
| ep 4 – | Sarah tells us that "Mark" jumped 2.362 metres at the last Olympics. Since when is the high-jump measured in millimetres? |
| ep 4 – | As the Doctor is being 'herded' through the underground complex, watch the right-hand wall wobble quite badly when the second door closes. (In fact, this happens more than once while the Doctor is in the complex.) |
| ep 4 – | When the Doctor enters the lift to leave the complex, the rear wall of the lift does not have any coats, caps etc. on it (or even hooks to hang them on), unlike when he both enters and leaves it in the Underground station. |
| ep 5 – | Whitaker's demonstration of rolling back time involves Butler raising a mug above his head and smashing it. However, in the action of raising it, he accidentally bumps it into that glowing red piece of apparatus hanging over him, making a loud "clunk". |
| ep 6 – | Criticising the dinosaur effects in this story is like shooting fish in a barrel, but special mention must be made of the gravity-defying tyrannosaurus at the start of this episode. As it chews on the brontosaurus, it leans over at a ridiculous angle, with its body almost parallel to the ground! |
| ep ? – | When we see the Tyranosaurus's arms, notice that it has three fingers. Unfortunately, in reality T-Rex had only two fingers. |
