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: During the scenes with the cast on the bridge, there are clear traffic directing cones and lights visible in the distance, depending on the angle. This was done to prevent people and traffic from getting onto the closed set.
Suggested correction: Incorrect. They make a point of showing that there are "Bridge Closed" and construction signs on the bridge, and you can even see some construction equipment on the bridge itself. The cones and lights are not there to prevent people from getting onto set... they're part of the set dressing, since the bridge is meant to be closed down for construction in the scene. That's why they chose the bridge as a meetup point... there will be nobody to interfere.
Revealing mistake: Parzival heads back to the Halliday Journals to watch the scene of Halliday and Morrow parting ways again. There is glass between him and the scene and some camera angles show Parzival through the glass from inside with the scene reflected on the glass. However the reflection is wrong. Morrow is standing on the right with Halliday on the left, but when showing their reflection in the glass, their positions are not reversed. (00:23:45)
Revealing mistake: Once Steve gets out of the police car and start shooting at the first merc, the merc hides behind a payphone. Many of Steve's shots can be seen sparking off the payphone that the merc is using to take cover behind, however not one single bullet hole or dent ever appears. (00:46:00)
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: In the opening montage, the article "Rucker Park today - The streetball Mecca" is also the rightmost column of the entirely diff different publication that comes in the following shot. (00:02:25)
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: The teacher has to stop the overzealous Stephanie from signing up to more than one task. Thing is, even before Anna Kendrick grabs the pen from the string, her name is written on the sheet already. (00:03:35)
Revealing mistake: After Robin starts to believe that the Teen Titans are in fact a joke, he gets sad and goes out a hole in the wall saying goodbye to them. He fires his grappling gun up and steps out of the wall. But his arm remains bent as he stands casually in the air to be taken upwards. There is no effect of gravity or any realistic body motion in those moment. As his weight should have had him dangle down with his arm stretched out above him and him swaying like a pendulum. Instead he appears as a stationary action figure in a single pose with his elbow bent as he's taken up.
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: Most of the car scenes entailed rain on the windows even though it otherwise had not been and was not raining, indicating the scenes were filmed on a rainy day. For example: Mary driving home; picking up Todd to go to the funeral; driving home from the church; driving back from rock climbing; and, Faith's car when she got to Luke's house. (00:17:35 - 01:34:12)
Revealing mistake: Vera types "Nico Lasarte - Murdered - 1989" into a web browser. When she clicks the search button and the screen changes to list the search results, Vera's position in the frame can be seen shifting on-screen, revealing that the shot of the search bar and the shot of the search results were two separate shots merged together. (00:57:20)
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)
