Factual error: When the hackers are trying to steal the photo from the woman's laptop, they turn up the TV to distract her. One of them clicks the smart TV icon and starts dragging the slider to increase the volume, which is all well and good, but we then cut to the hacker hammering the up key to increase the volume instead.
Continuity mistake: Lilo put candy on the counter: one green, one yellow, and two orange. The next shot goes to AJ. Then back to Lilo, and now the yellow candy has vanished, and the other pieces have moved around, indicating this is from a different take. (00:30:23)
Factual error: The opening scene of the Skyview collapse takes place on May 16, 1968, according to a newspaper clipping about the tower being closed for repairs as a result of Iris' premonition. During the vision, when the first bodies fall from the sky, the parking valets are listening to "Raindrops Keep Falling on My Head" on the radio. However, that song was written for the movie "Butch Cassidy and the Sundance Kid" and wouldn't be released until October 1969.
Continuity mistake: When Yelena Belova is found by the survivor scientist in Malaysia, she advances towards him, hands raised. However, she holds the explosive in her right hand in different ways between shots (check when she mentions the "breakthrough").
Plot hole: Reed's plan to teleport the planet away is based on the upscaling of the teleportation device he invented a couple of days prior. Every time he uses it, though, it uses TWO pads: a transmitter and a receiver. It takes the collaboration (and the power grid) of the whole planet to use the transmitter, but the receiver is conveniently absent. It would have invalidated the whole plan.
Visible crew/equipment: In the church at the beginning, there is a close-up shot of Sammy having flashbacks. A modern green LED light flashes next to the crucifix above the entrance door. (00:02:41)
Factual error: When Martin Krebs is sitting in traffic, he looks in his driver's side rear view mirror, and the writing "Objects in mirror are closer than they appear" is printed in a clear call-back to the first film. However, this repeats the mistake made in the first film: this writing is only on passenger side mirrors.
Factual error: At the end, Hunt emerges from a London Underground station called Trafalgar Square. The station that serves Trafalgar Square is Charing Cross. The spot used for filming is, in reality, a public toilet.
Other mistake: An on-screen graphic indicates the opening prologue takes place in Okinawa in 1986 and shows a scene from 'The Karate Kid Part II' of Miyagi explaining his family history to Daniel. While 'Part II' was released in 1986, it took place in the summer of 1985, since the events of 'Part III' are one year after the tournament in the first film, which took place in 1984.
Factual error: In the air battle with the Predator vs the World War 2 planes, Torres figures out the alien is tracking their heat. When he and the other pilot climb high to cool the engines, Torres cuts off his while the other pilot keeps his on. In the Predator's perspective, as soon as Torres kills his engine, the ship disappears from his heat vision. That's not how heat works. It's not just a light switch you can turn on and off. It would take time for the plane to slowly cool off and be invisible. (00:55:15)
Continuity mistake: At the wedding reception, the groom burns the prenuptial agreement to the shock of many. Charity looks down at it in shock. The scene cuts, and she's instantly looking up at the groom.
Continuity mistake: When Snow White comes back to life, she shows up at the castle and removes her hood. The way her hood falls around her shoulders differs between shots, plus the right side of the collar of her dress suddenly stands out between shots.
Continuity mistake: In the dark alley meeting between Jimmy Olsen and Eve Teschmacher, Sara Sampaio's hands change position on the jacket between shots a couple of times (for instance, at the end when she says "Ok" with a big sigh, her hands are under Jimmy's collar, but they were above it a moment before).
Revealing mistake: The computers in the bank have Excel running with the familiar yellow "Enable Editing" bar at the top, so none of the work the characters are doing would actually be saved. Either the main character is pretending to work, or he would be very disappointed when returning to his spreadsheet.
Continuity mistake: While Will is looking at the new storm clouds on Sandra's feed, he gets a message from the DHS director. On this message, it is displayed as "DHS Dir. Briggs"; then when he pulls it up, suddenly the title now reads as "DHS Director Briggs", with Director no longer abbreviated to "Dir.". (00:03:15)
Continuity mistake: After the female guard is lifted into the air by the witch, she falls against a bucket of yellow paint. Half of her face and her uniform are smeared with thick, bright paint. In the next shot, her uniform is noticeably cleaner and the paint on her face has faded to a light yellow tint.
Character mistake: Heidi Heatherley is referred to and addressed more than once as Dame Heatherley. Dames (and knights) take the title before the first name, so she should be Dame Heidi. It is surprising that a journalist, in particular, would not know this.
Factual error: Air Commodore Cyril Cooke is referred to as Sir Cyril. This is during the war, but he wasn't actually knighted until 1947.
Continuity mistake: When the bus is en route to Everest, there's an aerial shot of a road with a red building on the left and a large black billboard on its roof. The bus continues for several minutes, and after the hijackers hop on, the exact same aerial shot is reused.
