The Time of the Doctor - S7-E17
Continuity mistake: After the Doctor yells at Handles for putting him on the Dalek ship, the Doctor grabs him and carries the head with his right arm, then switches the head to his left arm. However, in the close-up as the Doctor asks, "What does this question mean?" we see Handles is back on the Doctor's right arm, but next shot as the phone rings, Handles is carried on the Doctor's left arm again.

The Time of the Doctor - S7-E17
Continuity mistake: When the Doctor teleports onto the Dalek ship and announces himself, he's holding up a broken Dalek eyestalk in the wide shot as he throws off his hood, but then in the close-up he throws the hood off again, with his arm lowered. Then he raises his arm again, with his arm bent at the elbow, only for a wide shot to have his arm sticking straight up, with his elbow straight. (00:00:55)
