Visible crew/equipment: At the time when they get lost and stumble back to the river and the log, and Heather says "No, it can't be the same log", look across the river. There is someone standing there clad in white, and all three of them are standing on the same side of the river...
The Blair Witch Project (1999)
1 visible crew/equipment mistake - chronological order
Starring: Joshua Leonard, Heather Donahue, Michael C. Williams, Bob Griffin
Factual error: In the beginning of the movie when they are in the hotel room they are drinking Killian's beer. However, the label on the Killian's bottle was a new style label. When the movie was supposedly shot the Killlian's would have had the old style label.
Heather Donahue: I tell you guys, two more hours max.
Question: Why is it that we never see the Blair Witch? Also the cover is very convincing that this is a true story. Is it?
Answer: The Blair Witch does not exist. The reason you didn't see is it is an abstract concept. What you can't see is scarier because you make her up in your own mind. It is a complete hoax of a story. The three actors have been doing many other acting jobs since, especially Heather and Josh.
