Visible crew/equipment: When Riddick's team reaches the crematoria hangar with the Necros already there, there are two "lensers". As the camera pans to the first lenser full frontal it turns its head, and in the glass of its face plate you see the banks of studio lighting and camera crew. But when the scene cuts to what it is looking at, you see rocks. The effect also occurs when the second "lenser" turns its head , but the visible equipment is less. (01:24:45)
The Chronicles of Riddick (2004)
1 visible crew/equipment mistake
Directed by: David Twohy
Starring: Judi Dench, Vin Diesel, Karl Urban, Thandie Newton, Colm Feore
Continuity mistake: The character Imam has a large animal tooth on a necklace. Later than 5 minutes and less than 25 minutes into the movie Riddick and Imam are having an argument where in different shots of the same scene two different necklaces switch back and forth. The first, which is a significant plot point later on, is longer and plainer then the embellished, more curved second one.
Toombs: [Arriving at Crematoria] If I owned this place and Hell, I'd rent this place out, and live in Hell.
Trivia: In the opening scenes of the movie there are several massive statues representing necromongers. These statues are also in the film Batman. They are right in front of the building when the goons announce that they will be running Jack Palance's company.
Question: Why was that one guy walking around with a knife in his back? Were some of the other Necromongers that way too?
Answer: In the novelization they say that Irgun received the wound but because the knife was so near the spine it would require major surgery to remove it. He opted to leave it in.
