Factual error: When Rose gets the message there are two things wrong with what you see on the phones screen: firstly on the top right of the screen you can see the icon for mute even though you heard the beep, and secondly that screen is for when you type in the number you want to call (text), not the screen for receiving a text.
Continuity mistake: When the Cyberman is hit by the electromagnetic bomb, it falls to its knees, then backwards. Yet in the next shot, it is flat on its back, with its leg extended. (00:25:20)
Continuity mistake: While hiding behind the mini-skips, Rose and Pete hold hands. After a cut to close up, they hold hands again. (00:08:55)
Continuity mistake: Pete Tyler holds the sonic screwdriver against a section of rope next to his leg, but it breaks below his feet.
Suggested correction: After the ladder breaks, and before we see Pete's feet again, we see him climbing a bit up the ladder. When his feet are next shown, he has them on the new bottom rung of the ladder. It would seem that the rope broke exactly where Pete was holding the screwdriver - right by his ankle.
Continuity mistake: When Jake turns on the light in the cabinet with the Cyberman on the zeppelin's bridge, he's holding his handgun in his left hand. The scene cuts away to Mickey briefly, and when it cuts back to Jake his gun has jumped to his right hand. (00:24:30)
Continuity mistake: When the Doctor and Mrs. Moore are walking through the tunnel of Cybermen, there is constantly a light source in front of them. When the shot looks ahead, there are no lights. This is due to the cameraman giving more light so this all can be filmed.
