Continuity: At the end of the movie, Riddick is in the ship, plugging in the power cells. Fluorescent lights flicker on and he doesn't react to it, even though he's not wearing his goggles that protect his light sensitive eyes.

Deliberate "mistake": In the scene right after they figure out that an eclipse would occur, everyone takes Shazza's drive to get back to the crash site. Right after the ride under the huge skeletons, you can see Shazza take a turn to her right but she was turning the wheel to her left.

Continuity: While exploring the abandoned settlement, Fry goes inside one of the buildings and finds the room with the planet system model. It then cuts back to Imam and Johns walking up to the machine that draws water and you can see that Fry is with them. But then it cuts back to her looking at the models of the planets to show that she was in there the whole time.

Continuity: After Johns dies and Riddick is talking to Fry you see in one shot that only the bottle that Fry is holding is lit up, yet in the very next shot you see that all three, Fry, Jack, and the Muslim kid's bottles are lit.

Continuity: In the scene where only the old man and the "girl" are left in the cave you see that there are only enough "light worms" to fill half of the second bottle, yet in the rest of the movie you can see that both bottles are full of "light worms."

Continuity: When the guy with glasses (Paris) is chilling with his fan, there is some material stuck out between his right ear and his right shoulder. In the next shot when he retracts the fan, it's gone.

Continuity: After Riddick stabs and guts the raptor, his blade is shining clean, not covered in the blue blood of the aliens.

Continuity: Fry is not holding a glow slug bottle when she is waiting for Riddick at the spaceship (no light visible on her arms and body). After she hears him scream, she dashes off and suddenly acquires one.

Continuity: When the group is travelling through the canyon near the end of the film, they are burning liquor to light the way, yet there is a lot more light than would be given off from this small flame. And none of it is flickering as would happen with a naked flame.

Factual error: The rock samples are from "22 years ago this month," and the solar model predicts a solar eclipse every 22 years. But in order for the sample records to be kept, they must be marked relative to an interplanetary standard. For the orrery to have consistently accurate meaning, it must be set to local years - revolutions of the mystery planet around the sun. One timekeeping is used for records that must be transferrable to other planets and the other for daily use like time of day, but the two cannot be mixed. This makes much more sense than applying the standard cycle to local time - it would totally ignore local events like day, night, and eclipses, all of which are very important.

Factual error: As cool as it looks, it is impossible for a planet to have two sets of parallel rings, because rings only circle a planet's equator.
