Revealing mistake: Near the end of the film when we see Rhodes shoot Larry in the chest, you can see an outline of something underneath his vest, very obviously a device/squib simulating being shot in the chest. (01:15:15)
Continuity mistake: When Sam is talking to the P.I about "Taking care of Max," he gets into his car and the window is up. A few seconds later, the window is down. There wasn't enough time for him to roll it down. (00:54:50)
Continuity mistake: While Father Malone is drinking his wine you can still see the cork laying on the table. He finally gets up to try to catch Bennett before he leaves and the cork has mysteriously put itself back into the bottle. (00:05:00 - 00:05:45)
Continuity mistake: The amount of Kris' blood on Jesse's t-shirt changes constantly when he's running from Nancy's house. (00:32:30)
Continuity mistake: After Jonathan saves the baby from the car he goes to the funeral. In the funeral he starts talking to the baby's father and while they are talking you see a bald man with glasses pass by and glance at the baby and then in another scene you see the same bald guy pass again. (00:59:30)
Continuity mistake: Something weird happens as the sheriff rolls under the closing gate. She's holding a shotgun before she drops to the floor, rolls under with empty hands (seen from both sides), and as she stands up she's got it back. What's weird is that her dropping and rolling is one continuous shot, so she must have deliberately thrown the gun offscreen as she fell to help her fit through the narrow gap. She doesn't throw it through the gap - we'd be able to see it on the other side. (01:02:40)
Continuity mistake: The left tail light of Sadie's car is broken when she picks up the unfortunate hitchhiker. The light works when she turns left off the road. (00:36:20 - 00:38:35)
Continuity mistake: In the hotel when the manager comes through the door, in the first shot the door is open, but the next time the door is closed.
Continuity mistake: Selene normally wears high heel boots. They briefly turn into flats during her caged fight with Varga, right before he betrays her. (00:26:40)
Continuity mistake: In the scene at the beginning of the movie where the flying vampires are chasing the security guard across the boardwalk parking lot, the positions of his arms as he is running changes back and forth between shots. In the close-ups of the guard's face, his hands are up, holding his hat down on his head. In the wide shots, his arms are down at his side. (00:02:45)
Continuity mistake: In the secret covenant, the amount of blood on Eve's white top decreases when Olivia the vampire doctor examines her wounds. This is most noticeable under the collar. (00:34:20)
Continuity mistake: When the group of girls first pulls up to the gas station and talk with Barney, the shadow cast by the sign is much longer than moments later when they leave. (00:11:15 - 00:12:50)
Continuity mistake: The last two pictures on the left on the wall going up the stairs change continually throughout the movie, at least 10 times. (00:24:35 - 00:26:35)
Revealing mistake: In the chase scene about an hour into the movie, Robert Loggia is shown entering the Liberty Tunnel, driving on a wet road. Note the vaulted round ceiling of the tunnel. Next, we see a series of shots of him in the tunnel, and then a shot of the sun rising over Pittsburgh as he is about to leave the tunnel. Here is the problem - the sunrise shot is taken from the Fort Pitt tunnel on a different day. Note the dry road, the barriers to the driver's left at the tunnel exit and the Fort Pitt bridge straight ahead. There is no place for the driver to make a left turn out of this tunnel. Also note that the POV is from the left lane. All the Liberty Tunnel shots show Loggia in the right lane. The next shot shows Loggia exiting the Liberty Tunnel and making a left turn from the right lane, causing a pile-up. (01:11:10 - 01:12:20)
Continuity mistake: In the scene where Ethan Hawke is talking through the safety glass in the barricade to the polite leader of the gang outside, the leader shoots the loud-mouth guy standing to the right of him, using the pistol in his left hand across his chest. Immediately after that they show a top shot of him dropping his right hand holding the gun. (00:46:00)
Continuity mistake: When Beverly is in the bathroom she puts out her cigarette on the cubicle wall using her right hand. The shot switches to overhead and she's now using her left. (00:12:10)
Continuity mistake: When the car rolls down the hill and crashes into the snow bank, snow is kicked up onto the car. Camera cuts and the snow has disappeared. (01:13:00)
Continuity mistake: When Agent Desmond is waiting to see Sheriff Cable, the position of the hand supporting his face changes between shots. (00:08:00)
Continuity mistake: After Johns dies and Riddick is talking to Fry you see in one shot that only the bottle that Fry is holding is lit up, yet in the very next shot you see that all three, Fry, Jack, and the Muslim kid's bottles are lit. (01:23:40)
Revealing mistake: Taylor finds Sparks hiding under a bed. Taylor then gives him a tissue, and when Sparks reaches for it, his hand passes through the frame of the bed. (00:49:05)
