Plot hole: How did Carolyn Fry get out of the cave in the canyon to confront Riddick at the Skiff? Riddick strained to roll the rock into the cave entrance, and he was a big, strong man from a position of good leverage. How did Carolyn and the other two push the rock out of the way so that Carolyn could get out? And, then, how did Carolyn mange to push the rock back into place? It was still there when she and Riddick came back from the Skiff to bring back the other two.

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.
Riddick: Back to the ship, huh? Just huddle together, until the lights burn out? 'Til you can't see what's eating you? Is that the big plan?
Question: When Riddick says that the monsters can track them because the girl is bleeding, and Jack is revealed to be a girl, is it her period that he is talking about? Did Riddick smell it, too?
Answer: Yes, it is her period. Considering that he lived in darkness for years, it's possible that he smells it too. It's also equally likely he realized she was a girl and that the creatures were all riled up and put two and two together. But the first explanation fits Riddick's character better.
