Revealing: When the mountain man is grinning at Jon Voight tied to the tree, you can see that his "missing" front tooth is actually painted black.

Continuity: In the scene where Lewis and Ed are in the canoe after setting up camp and Lewis is bowfishing while Ed is drinking beer, Lewis shoots a trout. You can clearly see the arrow hit the fish just behind its head in a close-up shot. When Lewis pulls the fish in, the arrow is through the middle of the fish's body.

Revealing: After Jon Voight has killed the mountain man and has tied a rock to his body so he can dump him into the river, you can see the "dead" man take at least two deep breaths right before he is rolled off the rock and into the water.

Revealing: In the famous "dueling banjo's" scene I noticed several errors revealing that the actors are not really playing their instruments. This happens throughout the whole scene. The banjo player is using a different picking technique than would be necessary to create the music heard. His finger patterns on the fretboard don't match the sounds heard. The guitar player strums when you hear individually picked strings and visa versa. Again, his fretboard fingering does not match the music heard.

Factual error: In the beginning of the film the setting is very late summer or early fall as evidenced by the reference to getting back home in time to watch the football game on Sunday. Yet the deer that Ed shoots at is in the early stages of antler growth that appears to be more typical of late spring or early summer. The deer also appears to be some exotic species, not one of the whitetails that are native to Georgia.
