Near the end of the film, Barb's battle van has four rear wheels in some shots, but two in others.
In the opening scene, when Barb is dancing, her nails are bright red. When she goes back into the dressing room after the dance her nails are French manicured.
As the girl is being electrocuted on the table, her hair, which is spread out on the table, keeps changing position.
After retrieving the memory of one of Schmitz's men, as the Directorate Colonel is talking about capturing Cora D, he picks up a metal tool which is covered in blood on the end. But then as he holds it the end of the tool is completely free of any blood. When he places it back on the tray, blood is still on it once again.
When Woman in Torture Room is being electrocuted on the table, Colonel Pryzer is touching the screen which a head is reflected in.
However, in the next scene, he is touching the screen which her status is momentarily reflected in.
After they repelled down the window with the grappler, one of the thugs chasing them clearly has a pistol with a silencer, or more accurately a noise suppressor mounted to it. When he fires this, the sound is like that of a non silenced weapon.
When Barb shows a license of prostitution while posing as a hooker, it says "Good Health as of: 1-07-19." The film began in 2017, but it is subtly implied that over a year passes from the shot of Barb looking out at the city from the car until the torture scene, so it could be 2019 by now.
At 0:31:15 -the camera is jostled.
When Barb emerges from the bubble bath, she covers the front of herself with a towel, but when she walks past a mirror, a second towel can be seen covering her backside.
As Barb Wire dances topless, a tape marker is visible behind her.
When Barb rappels down the wall on a rope after rescuing the girl, before they go out the window, you can see Pamela Anderson's roots showing, where she hadn't colored her hair. In the next scene, viewed from above, it is obviously a stunt person wearing a blonde wig, as there are no roots showing.
In the final fight scene where one of the goons is shot and falls off the roof you can see the inflatable bag he is meant to land on in the lower right hand corner.
The dog Camille gets no acting credit.
When the Woman in Torture Room is being electrocuted, in close-up shots, her mouth is open as she screams in pain. In the next shot, her mouth is closed while she is in mid-scream and then she opens her mouth while screaming.
Reflected in Charlie's eyeglasses.
When Barb says "Goodbye Axel," she puts on her motorbike helmet in a side shot, and reflected in the helmet is the camera and crew members.
Lighting equipment and a crew member in a blue shirt are visible for a few brief seconds twice during the opening dance sequence.
Reflected in Barb's motorbike helmet as she talks to Big Fatso.
When the soldier is asking for a dance from Barb, Curly says to Barb "Come on Pam." I.e., Pamela Anderson.
