Continuity mistake: After Gordon gets dragged across the sand by the magnetic collar, he lies 30 cm away from it, his right arm straight. Then West shows up, and angle back to Gordon, who's now just 10 cm away with his arm bent. If he had dragged himself upwards between shots sound had had to be heard.
Continuity mistake: After Gordon detaches West's boot off the magnetic collar, West raises, extends his right arm and hugs Gordon. A shot later his right arm is lowered.
Continuity mistake: When Gordon tries to detach West's boot from the magnetic collar, the position of his right hand on the boot changes positions depending on the shot.
Continuity mistake: When West's boot gets stuck to the magnetic collar, in the close-up shots it is firmly stuck, but in the wide angle of him falling backwards it is totally loose. This keeps swapping back and forth.
Continuity mistake: While trying to detach the magnetic collars, West's right hand is either holding Gordon's collar or not, depending on the angle.
Continuity mistake: After the mudpit scene, when the magnetic collars get attracted to each other, Gordon's jams on top of West's. When the shot changes it's the other way around.

Continuity mistake: When Arliss Loveless makes his appearance at a gathering, a giant bust of Abraham Lincoln is wheeled out. The head on this bust explodes and we see Loveless's head pop out in place of where Lincoln's was. When we see a close up of it, we see what was left of the bust around Loveless's head, yet instantly afterward in a wider shot, the remains of the bust disappear.
Continuity mistake: After the cornfield scene and the heroes fall into the mud river, their clothes and metal collars are seen to be covered in mud. In the next scene featuring them, their clothes are muddy but their metal ring collars are totally unmarked.
