Revealing mistake: At the beginning of the movie, the protagonists dump the corpse of an agent in the middle of nowhere. The guy is stone cold dead...but you can see the carotid pulse on the right side of his neck, under the fake blood. (00:03:10)
Revealing mistake: While they're finally on the rapids, the girl blindfold keeps changing position from her neck to her forehead. (01:40:59)
Revealing mistake: Callahan proudly shows to a policeman an issue of the Portland State University "Vanguard", the magazine that is publishing his comic. Looking at the prop, it is instantly suspicious because Callahan's name is all over it like he's a celebrity, and in fact, the article on it is nothing but a copy and paste of Timothy Egan's "Defiantly incorrect" article from The New Yorker celebrating John Callahan's talents in 1992. (01:12:55)
Revealing mistake: When Orm presents the weapons to Manta as a water hologram, Manta walks right through the hologram with half of his body. This arm passes through the hologram made of water and even makes a splash sound. However, there is not a single drop of water on Manta's completely dry clothing after this.
Revealing mistake: Margaret's car and the way it was situated relative to already-parked cars in the courthouse lot was awkward. When she was sitting in the car, the driver's side-view mirror was angled outward yet gave a clear reflection of her face. The car in the row behind her was too close and at an angle, which would have likely blocked her approach. The car to her left was angled like a "V" to her car. These suggest/ indicate a green screen was used. Margaret's car appeared to be parked in the through lane. (00:53:58 - 00:56:52)
Revealing mistake: The bottom third of the left-hand side of the screen is a "filler." At the top part of the left-hand side, there's a bicycle hanging on the wall, a square wall shelf, and a 3-Light Tree Floor Lamp. About two-thirds of the way down the wall, there's an inverted image of the items at the top - the angled edge of the wall (which does not line up with the rest of the wall because it's inverted), half of a bicycle wheel, the square wall shelf, and 3-lights of the floor lamp at the bottom of the pole. (00:01:54)
Revealing mistake: Eve says they need to make sure nobody gets shot, so she picks up Franklin's pistol and takes out the magazine to store them separately. However in this shot the magazine is completely empty with no bullets anyway. (00:53:40)
Revealing mistake: When the agent is questioning Fat Freddy after the cop finds him with coke and a gun, she puts a phone up to his face and says "say cheese." She holds the phone up to his face with the screen facing him. You hear the click and beep of the phone taking a picture, but when she turns the phone around, it's still on the locked screen with just the background and a clock. (01:06:45)
Revealing mistake: When Mary is talking to Luke in the kitchen, there are "moving shadows" on the wall to the left of the screen, apparently from the camera/film crew. (00:19:40)
Revealing mistake: The visiting nurse was using a non-functioning sphygmomanometer to take Dan's blood pressure. On-screen, the nurse compressed the air inflation bulb about 10 times without the gauge (measuring unit) moving. The nurse compressed the bulb about 10 more times - a ridiculously high number (about 20 total) - but it could not be seen if the gauge ever moved. (02:11:10)
Revealing mistake: Obvious stuntman when Luke's kicked down the yacht's stairs by Maddy.
Revealing mistake: The paper towel holder is in front of Mr. Truett when he joins his son at the diner table. After Zach leaves, Mr. Truett moves the tray off the table and (off-screen) probably moves the paper towel holder to his left where Zach was sitting. However, some shots show the paper towel holder too close to Dave (which would be near the middle of the table) while other shots show it at the edge of the table (in front of Zach's empty chair). (00:20:35 - 00:21:40)
Revealing mistake: Davey at the beginning of the movie is looking at the newspaper he's delivering to Mr. Wayne Mackey. Just from a glance at the page you can tell that something is off, since the article supposedly about a missing boy appears to be written entirely in first person. Upon closer inspection, turns out that it's filler text from chapter IV of Robert Louis Stevenson' s "Treasure Island". (00:01:30)
Revealing mistake: Vera is handed a cup of coffee at the crime scene. After taking the first sip, no liquid can be seen against the area of the cup she drank from, revealing that there was nothing inside it. (02:00:40)
