Revealing mistake: When Claire jumps down into the silo filled with apples, the whole top layer of apples bounces, which indicates that there is only a thin layer of apples instead of apples all of the way down. Soft material would have been under the apples during filming. Rotting apples wouldn't have that sort of give normally.
Visible crew/equipment: After the exterior shot of Paul and Rebecca flying the new radio-controlled airplane it cuts to Rebecca sleeping, and when Claire appears at the doorway we can see the boom mic moving around overhead in the hallway, while she and Paul talk. (00:07:05)
