The Three Doctors: | ||
 | ep 1 – | Dr. Tyler starts to unscrew the top of his instrument package, and before he can finish undoing a single screw, he gets zapped by the anti-matter blob. Immediately after he vanishes, though, we see the lid of the package completely off and lying loose on top of the box, so that the anti-matter blob can emerge. How convenient. |
 | ep 1 – | Despite the Brigadier claiming that UNIT HQ is a "top-secret establishment", it boasts a large sign outside telling the world not only the function of the building, but the name of the commanding officer! |
| ep 1,2 – | The Doctor drives Bessie into the UNIT garage, with Jo holding a large umbrella over them. She folds it up and puts it on the floor in the back of the car. Bessie then gets zapped by the anti-matter and disappears. But in episode 2 when they find Bessie in anti-land and drive off, the umbrella is nowhere to be seen. |
| ep 1-4 – | Whenever the scanner is used, it shows a picture of the lab with the TARDIS in one corner. But if the scanner is mounted on the TARDIS, how can the TARDIS be in the picture? |
| ep 1-4 – | Several scenes take place in the Doctor's lab with the big chunk hewn out of it. Toward the end of episode 4 it is especially clear that the jagged wall is styrofoam. Props are often made with styrofoam, but it's usually not left a glaring white! |
| ep 1 – | The Second Doctor's recorder can be seen sitting on the console before it supposedly "materialises" and is noticed by the Third Doctor. |
| ep 2 – | Bessie was supposedly transported into anti-land, but when you first see it sitting there, it has dust all over the tyres as if it had just been driven to its destination. |
| ep 2,4 – | You can see the reflections of some camera crew in the monitor used to display the First Doctor. |
| ep 2-4 – | When Omega is looking at his "magic screen", you can see the outline of the actual television set at the edge of the image. |
| ep 2 – | Dr. Tyler tries to escape from Omega's palace, and runs into a Gell Guard that turns to face him, then comes after him. In his haste to get away, he grabs the wall, causing it to wobble noticeably. After he's gone, the Gell Guard then walks straight into the wall! |
| ep 2 – | After UNIT HQ disappears, you can see grass where it used to be. But how can grass grow underneath a building? |
| ep 3,4? – | When UNIT HQ lands on the antimatter planet, the Brig opens the door to see a still photo of a desert CSOed into the scene. Later, when the Doctors and co are trying to get out of Omega's stronghold through the big doors, you can see the exact same CSO shot of the desert outside. I guess that the BBC's library of clip photography isn't big enough to hold two different desert shots... |
| ep 3 – | When the second Doctor, the Brigadier and Benton emerge from the TARDIS, the doors are left completely open with the camera looking straight into them for ages, revealing not only the emptiness of the police box shell, but also that there's a pair of secret doors on the opposite side!
[These come in handy during episode 4, allowing seven people to come out of the police box in the final confrontation with Omega!] |
| ep 3,4 – | At various times, you can see actor Stephen Thorne's lips through Omega's mask (and in one profile shot you can also see his jaw), yet when his mask is removed, we find that Omega has been dissipated and has no face. |
| ep 3 – | The Time Lord President asks the first Doctor to go into the black hole, saying "All three are needed to defeat Omega." Considering that earlier the Time Lords had no idea who or what was attacking them, how did the President learn the identity of the enemy? |
| ep 3,4 – | When the Brigadier and co. arrive back at UNIT HQ in episode 4, the TARDIS doors that were left gaping open in the previous episode are now closed and locked! |
| ep 4? – | As the doors of Omega's stronghold are being pulled open, you can see that the exterior of the doors is smooth and gold-coloured. All of the exterior shots show the doors as being gold, but covered with a rocky texture! |
| ep 4 – | When the companions are returning to Earth via the pillar of smoke, you can see and hear each person walk up the stairs and then supposedly disappear. Unfortunately, you can then clearly hear them walk down the other side! |
