• Crew or equipment visible

    When Cole chases Hooker into the dead-end alley and is subsequently killed by Salino, the trigger for the squib can be seen in the actor's left hand. You can also see how he uses his thumb to operate it.

  • Crew or equipment visible

    In the scene where Salino is killed, as the gloved man runs toward Hooker, someone appears on a rooftop in the background and witnesses the murder scene.

  • Revealing mistakes

    When Salino is killed, the weapon in her hand is a revolver with a silencer. Since the cylinder of a revolver does not seal against the frame of the gun, a large amount of gas escapes and render the silencer mostly useless. Anyone looking to minimize noise would not use a revolver.

  • Revealing mistakes

    In the scene where Salino is killed, it is very noticeable that the bloody "bullet hole" which appears on her forehead is actually paint being squirted by someone standing beside her.
