Other mistake: When Amy's age is given as 1306, the computer screen reads 1308 instead. (00:15:50)

The Time of Angels (1) - S5-E4
Continuity mistake: When the Doctor and Amy are in the museum looking at the Home Box, after they steal it, they run to and enter the TARDIS, which is parked at the end of the hall by the last glass case. However, in the first shots of them in the museum, the camera was pointed directly at that spot, and the TARDIS wasn't there. (00:01:30 - 00:02:00)
The Time of Angels (1) - S5-E4
Continuity mistake: When the Doctor leans on the glass case with the home box, he clasps his hands together. In the next, wide, shot, his hands are separated and in loose fists. (00:01:48)
The Time of Angels (1) - S5-E4
Continuity mistake: When Alistair confronts River, the two guards with him stop and point their guns at her as he walks forward, changing position between the wide shot and the following close-up of Alistair. (00:03:05)

Continuity mistake: When River shows Amy and the Doctor the video of the Angel, next to the Doctor on the ceiling is a bar with two cloth handles, one on each end. The Doctor accidentally rips off the handle closest to him and the viewscreen. A minute later when Amy is alone and we are looking at the Angel video, this handle is back up. It's gone again in subsequent shots.
The Time of Angels (1) - S5-E4
Other mistake: At the end when the Doctor is seen shooting the gravity globe, he does not actually move his finger but the pistol still fires.
Revealing mistake: When the Doctor's jacket is being held by a Weeping Angel while he's monologuing about why they haven't killed him yet, he moves at one point and the Angel's hand moves with him, despite the fact that they're normally effectively stone in situations like this. (00:12:16)
