Revealing mistake: They let us see the stunt double's face for the girl Steven Seagal is fighting in the ending Cathedral scene, and she looks nothing like the actress.
Revealing mistake: When the American man throws a square concrete tile at the monster it reacts (moves its foot in pain) before the tile actually makes contact. (00:16:11)
Revealing mistake: Cruise and Lugnut are driving home along a road after speaking with Mr. V8 and Coupe about the race. For the entire four minutes of this scene, the shadow of Cruise's wing mirror cast on the road passes under the road markings, when it should be cast on top of the markings. (00:04:00)
Revealing mistake: Right after Sage plays chicken with the cops, the cop car is shown peeling out in reverse to follow her down the alley. The dust from the burnout is ejected towards the back of the car. Being a Crown Vic, the car has rear wheel drive but the dust should be moving opposite the car's direction. What this shows is that the car was actually being pulled backwards as it attempted to accelerate forwards. What's more is that even the sound is of a car spinning its tires opposite to being dragged. (00:12:50)
Revealing mistake: At one point in Heat Miser's song, he eats two fireballs. Directly above the second fireball you can see the reflection of string used to hold it up.
Revealing mistake: Throughout the scene when it is revealed that Jack has been offered a six month trial with the local team, the wall clock is stuck at the same minute and second. (00:18:30)
Revealing mistake: When Lindsey runs to answer her phone after she asks Slevin to explain why he was still wearing a towel, you can see the tattoo on Josh Hartnett's left shoulder blade coming through the makeup.
Revealing mistake: In the scene where the group of unlucky virgin sacrifices make it to the Minotaur's sleeping chamber and are banging on the door trying to get out, one of them is gored and lifted into the air. When this happens you can see the harness and wires (the cables are about 1/2 an inch thick and black, one either side of the body). In the same shot the clothing of the gored victim is bunched up over the cables also. (00:47:40)
Revealing mistake: While Suit is in a coma, there's a closeup of the monitor beside his bed showing Suit's vitals, and at the top of the monitor's screen are the words "adult simulating," with the timed "simulating" flashing off and on. There's also a strip of narrow filament tape covering "simulating," but the tape is transparent, so we can still see it flashing. (01:17:25)
Revealing mistake: When Phoebe is looking at herself in the mirror, she's trying to find out why she isn't attractive enough for roles. When she takes her bra off and inspects her breasts, it's painfully obvious that that is not her real torso, as her head kind of bobs around in a strange fashion, showing that her face/head was superimposed onto another woman's body.
Revealing mistake: When Michael fast forwards through traffic for the very first time, right before he hits the slo-mo button on the female jogger, if you look inside the circle part of the remote, the graphics are missing.
