In the beginning of the film when the main characters are driving to Whiskey Hollow Road there is a GPS holder that appears, and then disappears.
At one point in the film Mike says he puts on a hat to keep his head warm. However the hat disappears when he gets in a fight with Steve later on, and then reappears when he is hanged.
During the bloody dead animals scenes, the dead animals are clearly fake.
When the main characters are sitting in Steve's car in the driveway at the very beginning, other cast and crew members can be heard talking softly in the background.
When driving through Whiskey Hollow Road, the script is visible in the reflection in the window resting on Kevin's lap.
When Kevin first finds the piece of bloody cloth on the stump, other crew members are heard talking.
The script and camera bag are seen behind some of the chairs during the camp scenes.
At one point, Mike calls Kevin and Sidney. However, during an early scene it was said that all the cell phones were destroyed except for Morgan's and Steve's. Therefore Kevin and Sidney wouldn't have working phones to call.
