Attack of the Cybermen: | ||
 | ep 1 – | In a couple of the early TARDIS scenes a scorch mark is visible on the console room wall, next to one of the pillars. However, this mark isn't supposed to be there until Russell accidentally fires a Cyber-gun at the wall at the end of the episode. |
| ep 1 – | When the Telos work party member (played by Pat Gorman) gets shot by a Cyberman, he knocks the camera as he tumbles down the hill, causing the picture to shake. |
| ep 1,2 – | In the cliffhanger scene, the TARDIS doors are open (obviously) as several Cybermen enter with Lytton and Griffiths, while Russell attacks (and is killed by) a Cyberman already in the ship. The very next shot shows the intruders standing near the now-closed TARDIS doors — but there was neither time for them to close, nor was the usual door-closing sound effect heard. |
| ep 1,2 – | On both episodes, designer Marjorie Pratt's credit has obviously been crudely inserted into the end titles sequence, as it causes a noticeable "jump" in the starfield background.
[Apparently her credit was initially omitted by mistake, and had to be hurriedly edited in later.] |
| ep 2 – | The guard-railing on the tomb set seems to be rather flimsy during the struggle between the two Cybermen — it wobbles badly as one of them knocks it. |
 | ep 2 – | When Lytton stabs the Cyber-Controller, his "blood" splashes onto the camera lens. |
| ep 2 – | In the "fight scene" between the Doctor and the Cyber-Controller, the carpet on the studio floor (under the central console) gets kicked up and rather badly creased. |
