Continuity mistake: When Heather first picks up the bundle of sticks she carries them to the river. During this she steps over a log on the ground and if you look closely you can see the black bag containing the guy's teeth fall out but when Heather opens up the bundle it is still there. She couldn't have put it back herself.
Factual error: Notice at the beginning of the movie when they are loading their stuff, you see a 1997 or above Ford F-150 truck sitting at the house across the street. The movie takes place in 1994.
Michael Williams: I could help you, but I'd rather stand here and record.

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.
