Other mistake: When Oscar finds the business card under the swing, the narration doesn't match the writing on the flip side of the card.
Visible crew/equipment: In the shot where Faris is running to Evans's room to get him away from his one-night stand, as she passes the staircase you can see a shadow with movements that don't coincide with those of Faris. Deductive logic can be used to determine that this shadow is that of a member of the crew.
Other mistake: In the scene near the start as Will Atenton is being driven to his house by the property agent there is a close up of the car which shows a snow covered bonnet therefore the car would not have been driven very far as the engine was not warm.
Continuity mistake: When Alan is taunting Michael about selling door knobs and Michael's back is against the door frame to the dining room, the dining room is dark; both chandeliers are off. All four characters are in the living room but as Michael responds to Alan's taunts, the lights are on, even though no one entered that room and Michael's hands were in his pockets during the exchange.
Continuity mistake: Three-quarters into the film, Jacob brings Rosie, the elephant, to Reece Witherspoon's tent. Her husband, August, appears and seconds later there is, out of the blue, a cigarette between his fingers.
Continuity mistake: When Conan first fights Remo, Conan places a blood stain on his forehead by pressing his sword to it. Remo then runs off, and Conan gives chase immediately, pausing only to get Tamara on his horse. The stain is still there when Conan mounts his horse. The next time we see them, Conan and Tamara is still chasing Remo, but now Conan's face is completely clean. It is highly unlikely he would pause in pursuit of one of his father's killers to wash his face. (00:47:55)
Factual error: The security guard in the bank is carrying a revolver as a sidearm but has semi-automatic magazine pouches on his duty belt.
Visible crew/equipment: When Frank enters his office a boom mike dips into view for a split second, when the camera pans away from his co-workers laughing about the American Superstar contestant.
Visible crew/equipment: The two protagonists are on their tour bus, driving to the tourist pick-up spot. When they get there and get off the bus to greet the tourists, you can see in the shadows behind them the real driver shifting into neutral and trying to sneak out of the way. (00:05:35)
Factual error: Rochester Castle is seen standing alone and isolated from any other settlement. In actual fact it stands on the edge of the City of Rochester and very close to Rochester Cathedral, both of which certainly existed at this time.
Continuity mistake: In two scenes featuring close-ups of the fireplace days apart, the same logs are burning.
Character mistake: Nicolas Cage looks up the Bing results for Alan Marsh, the journalist he accidentally kind of murdered. The URL of his personal blog, hosted by the newspaper he works for, spells "blog" wrong. (00:55:25)
Continuity mistake: At the end of the movie, the bloody handprint on the car changes entirely the second time it is shown. (02:02:45)
Continuity mistake: Dr. Mario Tirelli at the beginning of the movie enters the clinic where he works. A blonde woman walks in the opposite direction and exits through the door as Tirelli briefly hails a nurse. At the cut, Tirelli is in the same spot as before (nothing changes in the background) but the blonde is back and with still a way to go before the door, and the nurse is far back too, with the doctor's hand not moving to greet her, in a different take entirely. (00:03:00)
Continuity mistake: When Frisson is giving the adder to the girls, the adder is going to go leave the jar through the hole but in the following shot, it is resting at the bottom.
Other mistake: In the hospital, Barrett had his right arm in a sling and his lower left leg in a cast. When the police/ detectives were trying to find Barrett, one detective said Barrett could not have driven himself somewhere because he had "a cast on his leg." The cast was on the left leg, so Barrett could have driven using his right leg, as usual. Maybe he couldn't have driven with a cast on his right arm, but the detective gave the wrong location of the leg cast. (00:50:30 - 01:13:45)
Deliberate mistake: The driver's side mirror would not be able to capture the view of the store that Monique is robbing - the mirror is slightly angled towards the rear of the car, plus Arthur's car is parked too close across the street. (00:00:33)
Continuity mistake: In the scene in the kitchen when Helen is telling Joe that she is pregnant, Joe is wearing suspenders over his shoulders. As the camera moves back and forth between the characters during the dialogue, Joe's suspenders "disappear." When the camera pans out, you can see that they are now hanging below his waist.
Continuity mistake: After Sarah finds her father in the bedroom and goes downstairs to get help, the blood pattern on her shirt/upper breasts changes. While the movie is edited to look like one continuous shot, it was filmed in bits and pieces, and the blood pattern was not consistent in some of the shots, it seems.
Plot hole: When Sam first encounters Dan, the headmaster, Dan reveals that he had to quit his musical career when he impregnated and married a groupie, but that he loved his daughter. Later, Sam runs into Courtney behind a liquor store, and Courtney, who is actually Dan's above-mentioned daughter, discusses her "aggro older brother". If Dan's original error in timing resulted in a daughter, how could she have an older brother?
