Continuity mistake: Near the start, Julie sits on a sofa when discussing the bribe. In the wide shot, as she says "I wish it were that simple", she rests her left hand on her knee. It then cuts to a closeup for her next line, and her left arm is suddenly along the back of the sofa. (00:13:40)
Continuity mistake: When Peyton returns to his lab after its destruction, a burnt picture of him and Julie is on the floor. The destroyed picture shows half of Peyton's face missing. After finding a new place to stay, when the picture is put into the scanner, more of Peyton's face is visible. (00:28:10 - 00:30:40)
Continuity mistake: When Durant shows up at Darkman's hideout in a helicopter, he is holding a machine gun. In the next shot, he's holding a grenade launcher. (01:10:20)
Continuity mistake: In the opening battle at the warehouse, there is frantic gunfire and battling during the scene. However, after the second car crashed, all of Eddie Black's men are suddenly dead, despite almost all of them being alive just a few seconds earlier.
Continuity mistake: When Durant fires a grenade launcher at Darkman as they are flying through the city, Durant hits a van with a clown face on it. A few seconds later Durant hits the exact same van again.
Continuity mistake: When the power goes out in Peyton's lab (when he figures out the secret of the synthetic skin), the entire lab is still filled with some light. If it was daytime, this would be believable, but it is night outside.
Continuity mistake: At the climax of the movie, in the skyscraper construction site, there is a segment where the villains are swinging large wires with metal hooks to hit Peyton. However, the number of wires swinging through the area changes during the course of the shots, and in fact, they all disappear for a period of time.
Continuity mistake: When Darkman's hand is pinned to the steel beam by the rivet there is no blood. When we see a close up of him trying to pull his hand free, there is now blood coming from the wound. When Strack calls Darkman a freak, Darkman gets angry and the blood from his hand is gone. The next shot of his hand shows blood, as he pulls it free from the rivet.
Continuity mistake: When Darkman and Durant are battling on the helicopter, Darkman drops a large hook and line from the helicopter. A few shots later, during one wide shot, the hook and line have vanished, only for them to re-appear when Darkman falls from the helicopter and catches them.
Continuity mistake: The villain fires with a nail-gun at Darkman and the nail flies for several seconds towards him. But Darkman is very close to the villain, the nail would have hit him in a tenth of a second.
Continuity mistake: As Darkman attaches the hook and line (from the helicopter) to the front of the truck, in at least three different shots, the position of Darkman's entire body changes. For example in one wide shot he is crouched over, then in the next shot he is standing up, etc.
Continuity mistake: When Durant and his thugs attack Peyton, as Durant asks about the memorandum, Peyton says he doesn't know what Durant is talking about. To this, Durant replies, "Unfortunate." Durant is literally right next to Peyton. Durant's thug then grabs Peyton, and it cuts to a wider angle. Durant completely vanishes between cuts. Both shots are pointed in the same general direction, so Durant should be (very) visible in the background of the wide-shot.
Continuity mistake: When Durant walks into Louis' office, after he places the glass on the table and says he's got good and bad news, his arm is either stretched out or not depending on the angle.
Continuity mistake: At Peyton's lab, after Julie tells him she can't help him and walks down the stairs, wooden crates suddenly appear on the floor between shots.
Continuity mistake: When Durant exits the courthouse the passers by are not continuous between shots. Furthermore, a woman in red reading a paper walks by twice.
Continuity mistake: When Durant is arrested, he places his right hand over his left wrist. The cop handcuffs his left wrist but, in the following shot, Durant's right hand disappears and is replaced by the cop's hand.
Continuity mistake: During the dancing freak scene, Peyton holds an iron bar and looks at his reflection on a puddle. He lets go of the bar, which falls on the floor. He then takes his hands to his head, but the reflection on the puddle shows his arms at waist level. Also, in the following shot the iron bar falls on the floor again.
Continuity mistake: When Durant leaves his cigar inside a beaker by a lighter, the cigar points in a 12 o'clock position. When the shot changes it's at 3 o'clock. When Peyton crawls towards it it's back to 12.
Continuity mistake: When Guzmán finds the papers at Peyton's lab he holds them by the middle. When the shot changes he is grabbing them by the corner.
Continuity mistake: At the burn ward, the doctor sticks a pin in Peyton and says "he can't even feel it." Peyton is in an 11 o'clock position moving to 12 o'clock. When the shot changes he's in a 9 o'clock position.
