Continuity mistake: When Santana begins to "spit noise" to intimidate Riddick, the camera moves around him and we can see the station and some mercs in the background, one of which is Falco and he is alone, but then the shot changes and we can see Vargas next to Falco talking to him. The shot changes again to Santana and when he is lifting the box, we can see Vargas approaching Falco in the background.
Character mistake: In Pitch Black they established the system they crashed in (M-344/G) had 3 stars. Jack stated it when the 2nd sunrise started, and the solar system model also had 3 stars. In this film when Boss Johns starts asking about M-344/G he's told it is a backwater system with 2 suns and 1 habitable planet.
