When Toby is stopped at the very tense police checkpoint, it is clear that his car has no front license plate, which is illegal in Texas and therefore very noticeable to the police, but when the car was acquired it was stated that the car had a New Mexico plate, and New Mexico does not require front license plates.
At the 90 minute mark in the film, Texas Ranger Marcus Hamilton walks onto Toby Howard's property to question him since he is fairly certain that Toby had been helping his deceased brother Tanner rob several banks. Marcus admits to Toby that he's the man who killed his brother (albeit justifiably). Then Ranger Hamilton says: "Well, you could shoot me now and be within your rights." That statement is factually inaccurate in the state of Texas and throughout the United States. Property owners, residents, and tenants cannot use "deadly force" against a trespasser simply because that person is "on their property without permission."
The Albuquerque skyline can be seen from the Rangers' office window.
In the final scene, Jeff Bridges parks his car a ways from the house and walks up, with Chris Pine meeting him at his fence line. Bridges asks is he can sit, and then walks up to the house. When he leaves, his car is in the driveway, right in front of the house.
The actors in the film state several times that the foreclosure sale of the family ranch will occur on Friday. All foreclosure sales in Texas only occur on the first Tuesday of the month.
The patches on the Texas state troopers' uniforms is the old one from the 20th century, not the current one.
The FBI does not investigate all bank robberies. Their involvement is dependent on the amounts taken and several other factors. In the case depicted in the movie the FBI would have gotten involved due to the number of the same banks being robbed.
When driving off after the first heist, Tanner is seen taking off his right glove and putting the hand back on the steering wheel, In the next shot from outside the car, he is now wearing both gloves again. After the police cars pass them, Tanner is seen without the right glove again.
Texas Rangers don't travel together as partners. Each Ranger is assigned to a company, then stationed at a particular town in the company's area. (With a few larger cities having two or more Rangers). Therefore, Marcus and Alberto wouldn't have been riding together, or even stationed in the same town, which means Alberto wouldn't have been with Marcus on the stakeout, nor been with him to get shot and killed.
In the final scene, Marcus parks his car a ways from the house and walks up, with Toby meeting him at his fence line. Marcus asks if he can sit, and then walks up to the house. When he leaves, his car is in the driveway, right in front of the house.
During a scene near the very end of the movie, multiple pump jacks can be seen on the ranch property, but no tanks for storing the pumped oil.
The shot where Toby puts hydrogen peroxide on his bullet wound should have produced foam and at least a wince.
Though the movie is set in West Texas, the first two bank robberies supposedly take place in Archer City and Olney, Texas, which would be considered North Texas.
No car dealer sells a car with another state's license plate. The dealer would have removed the New Mexico tags and put on a temporary Texas paper license plate. A driver with a Texas Driver's License driving a car with New Mexican plates stopped at a roadblock would have been very suspicious.
When discussing the lack of video recording at the bank, the Texas Ranger refers to the failure of the Young County Sheriff to record the video. The bank, as evidenced by the reflection in the window of the police car, is in Archer City, which is in Archer County. The next robbery, in Olney, is in Young County.
When Alberto and Marcus are in the hotel room, Marcus puts his beer into the six pack case. The other five bottles clearly have red caps on them. When the scene changes position, none of the bottles have caps on them.
When Hamilton pulls up to the Archer City bank, he is told among the things taken was money from the cash drawer. But, that bank hadn't opened yet and they were told there was no money in the cash drawers and, upon inspection, found that to be true. So no money was taken from the cash drawer at Archer City.
When the Texas Rangers are first discussing the two bank robberies, they say that the two branches are of a bank that does not operate outside Texas, therefore the FBI "don't want it." Bank robbery is a federal crime--the FBI always investigates.
When the casino cashier hands over the check the name of the bank is incorrect. The check shows "Texas Midland Bank" when it should be "Texas Midlands Bank".
Blood and brain matter is seen inside Parker's hat after he is shot by Tanner, but no damage to his skull is seen. However, we don't see the back of his head and so it is possible that there is an exit wound not visible to us.
Tanner fires the AR-15 right handed but shoots the telescopic rifle from the hill top left handed.
Before the brothers cross into Oklahoma, the camera shows them both talking in the front seat. The next shot from behind the car entering Oklahoma does not show anybody in the front passenger seat.
When Toby and Tanner are escaping the bank robbery in the Ford Taurus, the exhaust note is that of a V8 engine, yet the Taurus SE has a V6 engine.
Texas DPS Troopers wear v-neck t-shirts as white undershirts are not allowed to be visible in uniform.
Alberto says, "Sometimes a blind pig finds a truffle". Pigs locate truffles by their keen sense of smell. They are able to identify them as deep as three feet underground. Probably not a mistake, but Alberto poking fun at the way Hamilton talks.
After Toby eats at the diner and leaves a tip at the table, he walks out to the parking lot to hear Tanner yelling "Start the car!" After robbing a nearby bank. Tanner runs to the car with cash flying everywhere while he shuts the door to the car a dollar bill gets shut into the door at the bottom. When there is the next shot of the car it has disappeared.
When Tanner and Toby rob the bank in Post, a girl sends a message to her dad on her phone. The time on the phone is 6:07 PM. Seconds later we see the wall clock in the bank, and it is at 8:40. Clearly AM, as it is morning.
When Marcus visits Toby, he strolls to the end of the porch and takes a seat in the furthest chair, in the sun. In the next shot, he's in the next-to-last chair, in the shade.
When Tanner and Toby drive into Post, the camera is reflected in Tanner's sunglasses.
Near the end when Tanner leads the cops up on the hillside. He sets his Ford pickup on fire and jumps out just before it rolls back down the hill. However the gear shift lever is still in 'park' just before he leaps out. No automatic transmission vehicle would roll backwards on its own in 'Park' even down a hillside incline. The engine's flywheel and the transmission's torque converter would be locked in the 'park' position. The truck would have remained stationary until it was taken physically out of 'park'.
Jeffrey Lamm is credited as Technorane Tech as opposed Technocrane Tech in the closing credits.
