Character mistake: When Carolyn first addresses Imam, she quite obviously pronounces his name "ell-mom," as though the capital I in his title were a lower-case L. It should be pronounced "ee-mam". We distinctly hear Ali call out his name in this fashion after the ship crash lands on the planet.
Pitch Black (2000)
1 character mistake - chronological order
Directed by: David Twohy
Starring: Vin Diesel, Keith David, Radha Mitchell, Cole Hauser
Continuity mistake: 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. (01:23:40)
Riddick: I truly don't know what's gonna happen when the lights go out, Carolyn, but I do know, once the dying starts, this little psycho fuck family of ours is gonna rip itself apart.
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.
