The first time the team members see Reid, Hankel is clearly standing behind the camera. When we switch to the teams point of view, they can see Hankel standing in front of the camera. When we go back to the shack, he is back behind the camera.
When Tobias is taking Reid's shoes off and Reid begins quoting the Bible, you can see a crew member through the crack in the barn door behind Tobias in one shot. The camera turns back to Reid, then back to Tobias and the crew member is gone- you can see trees/shrubbery.
