Goofs

(at around 4 mins) Wendy uses the schools camera for the yearbook, saying that she has to turn in the pictures for a deadline. But in the scene where she is picking up her diploma (at around 24 mins) everyone already has their yearbooks. Later, Julie asks to use the camera to get pictures of graduation to meet deadline.

In the tricentennial scene, a man in purple can be seen jumping out of the way of the horse. In the next shot, that was just a split second later, he can be seen ordering popcorn.

(at around 42 mins) Wendy's hair in the cemetery scene changes between shots.

(at around 1h 10 mins) Kevin's photo shows a shocked expression as a camera flash has gone off close to his face. However, when Wendy takes this photo (at around 4 mins), he throws his head back, making this expression after the flash has gone off, therefore after the picture was taken, resulting in a completely different picture.

(at around 35 mins) Right before Wendy says she needs a minute in private, it shows a back shot of her. She's holding the crumpled paper that has Ashley's cell phone number on it. After Julie leaves, Wendy looks to her left and the paper is out of her hands, on the desk next to her.

(at around 34 mins) In the tanning bed scene, Ashley and Ashlyn have no way to turn the bed off, but in real life all tanning beds have a START and STOP button right in the bed.

(at around 32 mins) In the tanning salon sequence the tanning bed is locked down by the rack of CDs above it that fall. Tanning salons are not allowed to hang or set anything above the tanning bed.

(at around 13 mins) Roller coaster seat restraints do not work with hydraulic fluid. They work with pressurized air to enable fast release in case of an emergency. The moment the braces shut, the computer checks for irregularities in the locking system prior to clearance.

(at around 57 mins) A cordless nail gun takes about two seconds to recharge, and cannot fire consecutive nails nearly as fast as depicted.

(at around 43 mins) The "last photo of Lincoln" is shown as Wendy points out that the crack in the picture (on Lincoln's forehead) is where he was shot. John Wilkes Booth shot Lincoln from the rear, below the left ear with a small Derringer pistol. There was no exit wound. While it is still a goof, it is possible this is a deliberate error injected into the film, as it is a common misconception.

(at around 14 mins) When the roller coaster is climbing the hill in the premonition, Frankie disappears from the roller coaster until he is seen filming Ashlyn and Ashley on the lift. However, Frankie is still there but he is only seen for a brief moment because a very dark shadow is covering him.

A premonition is only in the mind. So it makes no sense that the camcorder would attach to the roller coaster in the premonition, since that is outside the mental perception of Wendy.

It isn't. She may have seen the guy with the camera using it and taking it on the roller coaster, so there's no reason why it shouldn't figure in her premonition.

(at around 25 secs) The roller coaster used for the Devil's Flight is really the Corkscrew at Playland in Vancouver, where the first three films, and the fifth film, were shot. During the opening credits, the name "Corkscrew" is seen up in the lights above the coaster.

In the beginning when Wendy is taking photos, the digital camera makes a "reloading" noise which is only found on film cameras.

(at around 1h 26 mins) At the very end right before the camera shows Wendy, a dead body is seen in the lower right portion of the screen and right before the camera cuts away the body is seen blinking.

When Lewis is seconds away from getting his head crushed by the two iron weights at the gym, the weights are not level with his head.

(at around 47 mins) When the speeding car rams Kevin's car into Frankie's car, due to the laws of physics, Frankie's car should have gone forward but instead stays in the same position.

When Wendy takes photos before the roller coaster ride, the flash is accompanied by the sound of a very old filament flash bulb popping.

(at around 1h 6 mins) When Wendy and Kevin come out of the police station, after the first angle change, their spoken words do not match their lip movements.

(at around 56 mins) After the Lewis scene in the gym, a camera can be seen reflected when Kevin opens the door after Wendy asks him to drive.

(at around 46 mins) When both Kevin and Wendy are looking at the pictures after the funeral, Kevin asks Wendy to look at Frankie's picture. Kevin then turns the car a little to the left almost hitting the tow truck. The tow truck is seen in the metal bumper.

(At around 01h00) At the warehouse, after Ian knocks down a few items and triggers the other forklift to drive forward, a crew member is seen driving the forklift.

(At around 59 minutes) At the home improvement store, after Ian knocks down a few items that eventually trigger the forklift to drive forward on its own, a crew member is visible in the top left hand corner driving the forklift.

The film is set in Pennsylvania, however the "Build It" store prominently displays signage for Rona Home & Garden, a Canadian home improvement store.

After the premonition on the rollercoaster Wendy didn't take the photo of the ride operators hand waving in front of the camera but she did in the premonition so how did she have the photo on the camera later to see her sister on the rollercoaster?

(at around 55 mins) In several shots during the weight room scene, a boom mic is reflected in the hanging swords.
