As Taggart trips the first attacker with a stick at the lumber yard, all the other attackers can be seen already knocked down before he's even fought them yet. In the next shot they are all standing up again.
Early in the film, Jack is trying to offer a guy a ride, who refuses. The man who refuses the ride walks by the same car (and the same trailer) twice.
When Jack comes to arrest Orin, the blonde girl standing next to him at the table is moving behind Orin. In the next shot she's sitting again.
The sign on the side of Taggart's truck changes from Hanson Mining to the sign for the church, and back again, on both sides of the truck.
When the driver of the semi is ramming the pickup, every time he hits the brakes the semi speeds up and you can hear the engine rev up.
Near the end of the movie, Jack throws a flare towards one of the fake US Marshals who catches it just inches before it lands in a puddle of gasoline. Liquid gasoline is itself not flammable; but gasoline vapor is. Holding a flame inches away from such a large puddle of gasoline would ignite the vapors.
Taggert asks his boss to send him some agents for witness protection. And then when he meets the men at the gas station, the first one introduces himself as "officer" so and so. Most federal law enforcement agencies, including the EPA, regularly utilize the US Marshall's Service for its Witness Protection Program.
The EPA does not have the authority to make arrests or carry firearms. Their primary goal is to ensure total compliance of current laws and investigate violations with the intent of issuing fines, negotiating settlements and assisting federal prosecutors with lawsuits, either criminal or civil, in certain circumstances.
Many scenes in the movie take place in a bar in Jackson. Jackson is located in Breathitt County, which is "dry", meaning the sale of alcoholic beverages is illegal.
End credits: the producers thank the "Common Wealth" of Kentucky. Like several other eastern US states, Kentucky is a "Commonwealth" - one word.
In the snake scene, the 2 rattler are western diamondbacks, not native to that area. Eastern, timber or cane breaks are more likely.
When Orin Sr. is watching a showgirl rehearsal, one of his lackeys walks up to him, hands him a cordless phone and tells him it's his son. He pulls on the antenna and we hear the sound of a telescoping metal antenna, but it's a solid rubber antenna.
When Jack Taggart grabs the striking rattlesnakes, you can clearly see the wires attached to pull the snake dummies toward his hands.
After getting off the plane and driving into town, the camera car is visible in the windows of the houses.
At one point when Jack is being chased by the coal truck, his own truck slides sideways and stops. Jack gets his truck back into gear and speeds off revealing on the left of the frame that the coal truck is being projected on a screen.
Sarah is working her bee hives in a protective veil and gloves. These are to help prevent the bees from entering the clothing at the sleeves. Sarah is wearing a dress the bees could easily fly under and accidentally sting her when she moved. She should had worn slacks and had clips or bands at the ankle to prevent the bees from entering her clothes
