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)
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)
