Continuity: Jake Riley is chocking the Torch with a seat belt, the ambulance slides and hits the wall with the driver's side first. Front view shows the mirror on that side getting flattened. When torch drives forward again the mirror is back in its place.

Continuity: The angle of The Torch's gun changes repeatedly between cuts when The Torch is pointing his gun at Jake in the operating room.
Continuity: In the opening scene, we see the mother's bloodied face. The blood changes position between shots. Further, after the killer murders her, her eyes are open; as he takes photos, in some shots her eyes are closed and in others they're open again.
Continuity: As the Replicant escapes the car to warn the officers and Jake of the dangers in the Torch's apartment, he is carrying the bar attached to his handcuffs. However, when he is shown walking out of the building after the explosion, the bar and the cuffs are both gone. Then the cuffs re-appear moments later as the Replicant chases the Torch down the street.
Continuity: The Torch knocks out a nurse in the morgue. She falls on the ground, but her position changes throughout the fight scene.
Revealing mistakes: (At 2:57) When the Torch is lighting the $20 bill on fire, which of course is fake, but usually the camera is not close enough to see. This time however you can see "Motion Pictures" where it would normally say United States.
