Patrick Swayze hurt a knee during filming. He chose to make Ghost (1990) next because it was less strenuous, turning down the roles of Gabriel Cash in Tango & Cash (1989) and Mike Harrigan in Predator 2 (1990).

Marshall R. Teague initially didn't get along with Patrick Swayze. While filming their big fight, both men quickly realized they shared a dedication to realistic stunts. They developed so much mutual trust that they improvised a lot, and allowed each other to throw real punches and kicks. When Jimmy swings a log at Dalton, Teague mistakenly thought it was a breakable prop log. By the end, Swayze was covered in bruises, with two broken ribs and a busted knee.

Patrick Swayze's fame caused problems during filming. A group of middle-aged blonde women attempted to drive up to his trailer. A raft of Swayze fans sailed by while filming the big fight scene by the river. A female extra playing a waitress was too busy staring at Swayze to watch where she was going and tripped, spilling her drinks on another extra.

The film's original tagline referenced Patrick Swayze's success in Dirty Dancing (1987), "The dancing's over. Now it gets dirty."

According to Sam Elliott, all of the actors did their own stunts, "I fucking got the shit kicked out of me for the entire film." They were all trained by Benny Urquidez, a holder of nine black belts in nine different disciplines. Urquidez believed so much in Patrick Swayze's abilities, that he suggested Swayze become a competitive kickboxer.

Continuity

In the Double Deuce office, there is blood dripping from Pat McGurn's nose before Dalton hits him.

When Elizabeth joins Dalton on the roof, outside his bedroom window, their position and blanket moves over and out further away from the window in the front angle shot.

After Dalton has put the tires into the car, the boot lid wouldn't obviously get closed as there are too many tires in it. So the next camera perspective shows only Dalton closing the lid and doesn't shows the tires anymore.

When Ketchum and the three men walk to the Double Deuce to start the fight with Dalton, the tallest one in the back is a different person after they walk inside to confront the bouncers.

When Dalton goes to the hospital to get staples from Doc, he raises his left arm and you can see nothing on his biceps. Later on, you see bloody small cuts then they form into scars.



Factual errors

Throughout -a beer bottle thrown at a barrier made from chicken wire will not break on contact.

When Dalton's Mercedes jumps the wall at Wesley's house and explodes in flames, it rolls to a stop and one of the goons opens the driver's door bare handed, he would not have been able to do this if the car just exploded and caught fire.

At the time the movie was made, Missouri used two different license plates, maroon for cars, black for trucks. Emmet's truck - and possibly others - has maroon car plates.

The Ford station wagons crushed in the car dealership scene are purported to be new cars in the movie...but in fact when the film was made, they were all about four or five years old at least, possibly as old as 1979 models.

in the strip joint, the Marines are all wearing bdu's. this is illegal in the military to wear this uniform to any establishment that serves alcohol as its primary product.



Incorrectly regarded as goofs

When Wade Garrett rides up to the Double Deuce on his motorcycle, he isn't wearing a helmet. Missouri law requires all motorcyclists to wear helmets. However, given his persona, this may simply been due to him being a traveler to the area (not familiar with the law) or simply unconcerned with the law altogether. Furthermore, considering the absolute astounding lack of police presence throughout the vast majority of plot, it is hardly implausible that this law that would not be actively enforced (along with just about every other law in the area, apparently).



Revealing mistakes

When Jimmy hits Bear the bouncer with a pool cue, you can clearly see that Wade Garrett is pretending to be struck when in fact, he is not.

When Red's store explodes, it is revealed as a flimsy shell with none of the shelves metal shelving we saw earlier.

When Dalton and Wade are seen in the front seat of the Buick, the car appears to be mobile. Our view of them is through the windshield. There is a hole in the windshield right in front of Wade; however, his hair never moves from what should be a gust of air entering the vehicle through that hole.

After Red's store is done over, plastic bottles (of varnish?) on the shelf appear to have been squeezed until the contents overflowed, but still remain upright and neatly spaced.

In one famous scene, Wesley proclaims to have a cousin in Memphis that knows about Dalton's past regarding a homicide in self-defense. He says that the judge was told it was self-defense, which would indicate the trial was long over. Dalton seems shaken by the threat. However, this is an extremely weak, veiled threat considering double jeopardy trials are unconstitutional.



Miscellaneous

As in so many dramatic car jumps, cars just don't have built-in ramps to take flight. It is doubtful that Brad Wesley would have built an Evel Knievel ramp outside of his stone fence.

Travis McKenna is miscredited as Jack, though he's only ever referred to as Bear.

Audio/visual unsynchronized

During the dance scene with Denise in the Double Deuce (following the fire at Red's Auto Parts store), Jeff Healey brushes off Denise's hand but the music, specifically the guitar, keeps playing.

Around 58:44, you hear Jeff Healey singing "Let it roll, baby roll..." however he is not singing into the mic at all. Instead, his head is swinging back and forth as if he's playing a guitar solo.



Crew or equipment visible

When Red is reaching for the replacement antenna for Dalton, you can see a prop man handing the antenna to him.

When the monster truck destroys the auto showroom, you can see a chain under one of the "victim" cars, securing it to the floor to limit its movement.

Dalton's stuntman is visible several times during the movie, particularly when going over the Double Deuce railing when fighting O'Connor, and when fighting Brad Wesley at the end. He's much bigger than Swayze.

Reflection of lighting truck and crew on the side of the mustang when backing out of the driveway at Red's auto-parts store.

Shadow of camera crew visible on Dalton as he is performing Tai-Chi.



Errors in geography

After Wesley has Ketchum destroy Strodenmire's car dealership in Jasper, MO with the big wheel truck, you can see a highway sign behind Dalton that reads "Los Angeles" "Bakersfield," accompanied by mountains.

Set "Outside Kansas City," yet deserts and mountains are frequently plainly visible.

Supposed to be set in Jasper, Missouri, yet if you look carefully in one scene, you can see a road sign with a California highway marker in the background.

As Dalton and the doc drive away in her jeep, you can see a California Highway sign that reads Ventura, with an arrow. Wrong state!

When Wesley's henchmen are pulling away in the red Mustang after trashing Red's Auto parts, a sign identifying one of the buildings across the street as "California Tile and Home Center" is clearly visible.



Plot holes

If Wesley is the most evil and hated man in town, and is a man who does things like vandalizing or destroying people's businesses and homes, and even resorting to murder, why are the people at the car dealership cheering and smiling after he has one of his men destroy the showroom with his monster truck?

The town has chain stores, a hospital, and a fire department yet no police department.



Character error

When Garrett and Dalton are done fighting with Jimmy, Sam Elliott blows his next line. He says, "Same town, new story," a line which makes absolutely no sense, as they've never been here before. What he meant to say was, "New town, same story," which would have made perfect sense. Clearly, either the director missed the mistake, or felt that it wasn't worth the time, effort, or cost to re-shoot the very end of the fight just to correct that one line.

When Jimmy is dragging Denise out of the Double Deuce before the fight, he raises his left arm/hand to stop her trying to hit him. He does this before she even tries to hit him as he knows it was in the script. Most likely she was late with her trying to hit him.

[1:36:10] When Wesley calls the bar, Dalton answers, "hello" instead of "Double Deuce."
