Visible crew/equipment: While Jin is cuffed to the wreckage, Sun points to her wrist and explains in Korean, but Sayid shouts, "The cuffs stay on!" At the start of the next shot, a crewmember's arm is seen holding the reflector screen to Sawyer's left, as he makes a sarcastic comment.
Visible crew/equipment: As Jack, Michael, and Charlie walk up to Hurley, the camera goes to the left of Hurley and you can see a road to the right of him and directly behind him a fence.

Continuity mistake: When Kate leans over the unconscious marshal he wakes and chokes her, and when Jack subdues him the marshal's large head bandage falls off.
