When the military cargo plane with Oscar aboard is seen landing, it is a silver sleek-bodied jet plane, yet in the next shot of the plane taxiing, it is now a bulkier-bodied prop-driven plane that's painted in camouflage.
When the boy is riding his horse across the military grounds and watching the fighter plane taking off, the wide-angle shots show him riding along right beside a dirt road, but the close-up shots of the horse's galloping legs are on grass.
The large falling boulder that Jaime karate-chops in half with her bionic arm has a slightly metallic silver-gray color when it is first seen, yet when Jaime breaks it in half, it is a dull sandy color like the other rocks that are falling.
When Jamie is looking for Paco at the air base she is running with a white and blue top on then she stops to put her hand to her ear to listen for paco she has a brown turtle neck top on .
When petting the horse, Jaime is standing behind the RESTRICTED - NO ADMITTANCE sign, but then when the camera switches to a from-the-front view, the wording on the sign is still visible. No "restricted area" sign would have the same wording on both sides, or any unauthorized person would be obliged to stay where he was standing forever.
Some of the "restricted area" signs shown throughout the movie obviously face the wrong way (ex: someone who is supposedly trespassing is shown going away from a sign instead of toward it) and/or are posted in needless locations (such as inside an already heavily guarded/fenced-off area where only authorized persons would be, anyway).
Many of the boulders are too evenly/smoothly-rounded (some are even totally spherical, like beach-balls), and they are too fragile/powdery, so they look like they are made of brittle foam plastic.
At the beginning of the movie, the boy's chanting can be heard, but in a closer shot of him, his mouth is not moving.
When Jaime is jumping up and trying to catch the man with the flight suit after he's risen into the air, the wires that are lifting him can be seen in the top of the shot.
As Paco chases Jaime he glimpses the man in the jet pack and Paco pauses on his horse. Moments later the arm of someone in a light blue shirt is visible in the lower left-hand corner of the screen.
Jaimie keeps calling John 'Paco' Little Bear "PEY-koh", but that is incorrect. Since he is a Mexican, his name is Spanish (from Spain), and ought to be pronounced "PAH-koh". Otherwise, it would have had to be spelled "Peco".
Jamie is supposed to be unconscious, but when the two men lift her, she raises her head on her own.
