Continuity: When the Plasmavore drinks the Doctor's blood, she inserts her straw into his neck just under his jaw on the right-hand side. However, when Martha starts CPR on the Doctor after the Judoon leave, there is no visible wound from the straw's penetration.

Revealing: When the people in Hoovertown are meeting around the campfire, it's raining. However, everyone's clothes and hats are completely dry.

Continuity: When Lawrence is watching the weeping angel, just after seeing the Doctor's film/easter egg, he turnes away for a split second. By the time he turns back, you see the weeping angel's face only inches from Lawrence's face. Yet, you then cut to a wide shot were you see the angel's arms outstretched, so its face is about half a metre away from Lawrence's face.

Factual error: The army shoot at Martha's car and you can see sparks where the bullets bounce off her windscreen. But, at that close range, one of those things can go through a brick! I know you're supposed to allow a bit of disbelief, but this is taking it too far.

Continuity: When Mr. Copper is talking about how what they're doing could get them ten years in jail, the cut on his forehead changes sides.
