Audio problem: Right after Det. Corelli finds the limerick in her apartment, she pulls out her gun and there is a distinct sound of what's supposed to be her cocking the hammer on her pistol. However, Det. Corelli (along with all the other cops in the movie) uses a Glock semi-auto pistol, which does not have an external hammer that can be "cocked." The sound is added artificially, likely for dramatic effect. (01:06:30)
Other mistake: After the main characters are talking in a bar, the camera shows a wire above a street. On the wire, there are 3 pairs of old shoes hanging by the laces. However, a closer look reveals that 2 of the 3 pairs are NOT actual shoes, they are just cardboard cut-outs printed to look like shoes and they have the same graphic. (00:36:25)
Continuity mistake: 50 Cent goes through the window onto the floor below. There is glass and debris everywhere. Our heroes run past him later and there is no sign of the window debris.
Factual error: Spider's club is shown on 125th Street in Harlem, but whenever the officers radio in the location, they say 184th & St. Nicholas, which is in Washington Heights over 3 miles north.
Audio problem: As Turk is chasing Rooster through the rear of the club, they are running on concrete and there is the distinct sound of two sets of hard-heeled shoes, but Turk is wearing running shoes, which should make a squishy sound. (01:27:20)
