Between 10:39 and 10:47 a crew member's right arm & leg are glaringly visible and his right hand reaches around the frame of the doorway for unknown reason.
Again, between 11:07 and 11:14, the same crew member (right knee, calf & foot) is spotted crouching behind the same doorway. In the next shot at 11:20, revealing the area immediately behind that doorway where he was both times, the crew member vanishes.
