Blooper

David Arquette's teeth go back and forth from rotten and black to normal and white.

When the 3rd troglodyte sips from the flask, he immediately tosses it into the coals, but the cap is still on.

During the sheriff's first hand to hand contact with the 'cave dwellers' he is thrown to the ground and his hat drops, brim first, close to his head on his right hand side. In subsequent shots it alternates between this position and being on his left, turned upside down.

During the first scene where the 4 main characters are riding off to find the captives there are no provisions on the backs of their saddles. No bed rolls, saddlebags, nada.

When the metal flask is thrown into the coals, it is shown landing concave down, but when it is later picked up again, it is concave up.

Nearing end of the movie, when the captor attempts to shoot Hunt with Brooder's rifle, the "click" of the hammer drop is heard each time he pulls the trigger. After a lever-action rifle is fired, nothing happens if the trigger is pulled again. The hammer must first be cocked, either automatically by working the lever and chambering a round (as he later finds out), or manually with the thumb.

When right leg is wounded, one would use his crutch with the left arm. Hero's wife is a doctor: she would have forced him to do so.

He is left handed and shooting with his left hand. His Doctor wife would not have insisted he use his left arm to use the crutch even though his right leg is wounded and it would be proper use of the crutch. But not in a old west search and rescue mission hunting troglodyte monsters. He would be left very vulnerable using his non dominant hand to shoot.

In the scene of the first night of camping, when they dish out the hot soup, a kitchen towel is used to hold the supposedly hot pot, and the Sheriff's bare fingers are supporting it on the bottom. He's not actually touching the bottom of the hot pot though - he's holding the cool pot lid, then using that to support the pot.

At 1:30:22, when the Sheriff and his deputy are leaving Mr. Brooder, the troglodyte is seen to be breathing, even though he is already dead at that point.

The man with the splinted leg removes his boots after shooting the snake revealing a modern hybrid leather/rubber sole that looks suspiciously like a pair of Ariat boots. It would be about a century or so before boot makers produced boots with hybrid leather/rubber soles.

This movie was set at the turn of the century. When the stranger pays a dime for three songs and drops the coin in the jar, the piano player stated he knows the sound of Lady Liberty and prepares to play. Lady Liberty was on the nickel not the dime. The dime was called The Barber Dime and the nickel was called The Liberty Head Nickel.

That's what he was saying. That he knew the coin wasn't a dime, but a nickel.

Near the beginning of the movie, when the two deputies are playing checkers, the black checkers that are jumped are on the wrong squares. The black jumped checkers are on the white squares while the other black checkers are on the black squares.

On their first day out the three men ride across a wide-open grass field and the shot tracks them; near the end of it there is part of a two story modern house with roof visible behind a knoll.

One of the times O'Dwyer sets off on foot, he puts his jacket on. Then later, he takes it off. Still later, he puts the jacket back on again.

After the four men break camp the first night, they ride towards a large field that has been mowed by modern tractor-drawn mowers; the wide tracks made by pneumatic rubber tires are obvious.

Arthur is wearing current vintage thermal underwear as opposed to Wild West woolen underwear.

Patrick Wilson's boot soles are of a more modern type than those of the late 1880's.

When Kurt Russell declares, "Damnation" in the cave, his mouth doesn't move.

Why didn't someone stitch Arthur's cut on his leg? His wife had a medical background.

After brooder's hand is cut off, he requests his repeater so he can have a last stand against the troglodytes. Why would he request a two handed weapon instead of his pistol when he is missing a hand? Even if he had no more ammo for his pistol it certainly would have made more sense to trade the repeater for someone else's pistol.
