The Crossing - S1-E2
Visible crew/equipment: After Hank Dale tells Steve Pinkus that he wants to know "How it feels to get away with murder," Hank throws a punch, and in the next wide shot we can see the second cameraman's arms holding an additional camera, presumably to film the close-up, at the right side of the screen. (00:32:35)
Continuity mistake: When Katara is trying to heal the wounded earthbender, she gives Sokka the idea to take down The Drill from the inside. Sokka then stops her from saying anything while she is sitting down, and she is wearing her necklace. When she stands up in that same shot, the necklace is gone, like they forgot to animate it.
