Factual error: This film takes place in the north eastern USA. During the beautiful scene with the large black bird soaring above, they added a close up of an Andean Condor. The Andean Condor only lives in South America; Peru, Argentina, Chile, etc.
Factual error: The rifle on the wall and the one thrown off the cliff are 73 Winchesters but in the middle where it is being cocked it appears to be a 94.
