Pitch Black (2000)
Crew or equipment visible
Johns fires a shot, then the next round is the Red Shell. In reality, the red shell would be the last round to cycle into the chamber, because it is farthest up the tube. The rounds feed into the chamber starting with the last round fed into the tube.
It is also hard to see how even the eternal light could work in a gravitationally feasible system. It would have to be at their point of common rotation, assuming that was stable.
Incorrectly regarded as goofs
(however, given that the planet is continuously bathed in light, there would be no need to store solar power, so the equipment may not have had batteries.) This "correction" makes even less sense as (again) there would be no advantages to constructing a vehicle that runs only when light hits it. The panels can become dirty or even inactive, which is why there are BATTERIES in the system which are charged by the solar panels.
