The Vampires of Venice - S5-E6
Audio problem: When Francesco says "Did you just say something about Mummy?", his lips hardly move because of the fang prosthetic in his mouth, revealing that the line was dubbed back in afterwards. (00:39:00)

The Vampires of Venice - S5-E6
Revealing mistake: When the Doctor begins climbing a pillar on top of the bell tower, we can see white sky on the central arch. Two other arches in the very same shot show really dark CG sky. (00:42:17)
The Vampires of Venice - S5-E6
Factual error: Isabella is a black girl living in 1580 Venice. So how is it that she has perfectly straight hair, when modern hair care products won't be invented for centuries?
Amy's Choice - S5-E7
Continuity mistake: When Rory and Amy are running from the Eknodine, there is no mud on Rory's back, but he was thrown on his back into mud a minute before. (00:23:06)
Amy's Choice - S5-E7
Continuity mistake: When Amy puts on her poncho and says "If we're all gonna die, let's die looking like a Peruvian folk band", the slit changes orientation between shots as she walks to stand between the Doctor and Rory; from across her shoulders to pointing downwards. And no, she doesn't adjust the poncho onscreen to account for this. (00:27:35)
Audio problem: After landing, the Doctor comes out and jumps in place several times. As he does, the sounds of his landings don't sync up with his motions. (00:04:55)
Continuity mistake: When Amy is being pulled into the ground, there's a shot of her arms where the Doctor's hand gripping her left arm is missing. (00:13:38)
Plot hole: When the Doctor realises that something is coming up from below ground, he tells Nasreen and Tony that at the speed the three transports are coming, the underground arrivals will reach the surface in 12 minutes. The rushed preparations that ensue, including hurrying from the drill hall to the old church and setting up a surveillance network outside, couldn't have taken less than 12 minutes to set up, especially given that they also had to: inform the others trapped inside the shield (Rory, Ambrose and Elliot), inform Rory and Ambrose that their significant others (Amy and Mo) were missing, run between the old church and the block of houses and gather supplies. And, lest we forget, there's also Rory and the Doctor arguing about what happened to Amy and Ambrose's initial skepticism as to what is occurring.
Continuity mistake: Throughout this episode, Amy's earrings seem to disappear and reappear.

Continuity mistake: When Ambrose, while standing with Elliott, admits to killing Alaya, in the first shot, Elliott is standing in front and to the right of Ambrose. In the second shot, he's standing to her left. (00:27:52)
Continuity mistake: When the Doctor stands between Restac and his fleeing companions, using his sonic screwdriver to disable the Silurians' weapons, as the camera angle changes, the Doctor's grip on the screwdriver switches back and forth between pointing it at the lizards and holding it straight up and down, รก la the Neuralizer from Men in Black. (00:30:30)

Continuity mistake: Near the end, when the Doctor is explaining to Amy that she will forget Rory when the crack in time is finished eating him because he's part of her personal timeline, and he has his hands on her temples, Amy's hair is covering her ears in some shots, but not others. (00:40:56)
Continuity mistake: When Amy is trying not to forget Rory, the memory of him getting shot does not show the laser blast striking him. (00:41:44)
Continuity mistake: When the Doctor takes the piece of TARDIS shrapnel out and looks at it, he's holding it differently between the close-up and the wide shot. (00:44:05)
Vincent and the Doctor - S5-E10
Continuity mistake: When Vincent asks Amy "One of my favourite 'whats'?" his right arm is suddenly lowered even though he was just holding up one of his paintings. (00:06:40)
Vincent and the Doctor - S5-E10
Factual error: Amy inspires Vincent to paint sunflowers for his iconic Sunflowers painting. The episode takes place in 1890, even though Van Gogh completed Sunflowers two years earlier in 1888. (00:18:25)
Vincent and the Doctor - S5-E10
Factual error: By the time the Doctor and Amy meet him, Vincent van Gogh had already mutilated his ear. He should be missing part of his left earlobe.
Vincent and the Doctor - S5-E10
Continuity mistake: Amy's tights appear to be gone when she's watching Vincent paint the church. Previously whilst walking to the church they are on.

The Lodger - S5-E11
Continuity mistake: When the Doctor is flipping through a book while talking with Amy on his earpiece, in the close-up shot he's using his right hand, but in the wide shot is using his left hand, going through the pages the other way. (00:12:10)

Continuity mistake: At the beginning, when the Doctor takes Amy to planet One, he holds out his hand for Amy to take hold of when they're about to leave the TARDIS. When you see her from the back, Amy lifts her hand wearing her red fingerless gloves. But when it switches shot and faces Amy from the front, she takes the Doctor's hand wearing no gloves. When she steps out of the TARDIS, her gloves are on again. (00:04:54)
Chosen answer: No, no information is avalible for the identity of the entity.
