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)
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.
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.
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.
Other mistake: The Titanosaurs are somehow able to be completely hidden in grass that doesn't even reach waist level on humans.
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: A DC3 that flies at 198 mph max makes it from Europe to Alaska to Africa in a few hours.
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: 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).
Continuity mistake: When young Snow White places the flower crown on the girl, her braid swaps sides between shots.
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.
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)
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.
Other mistake: Martha, a woman of about 70 years of age, single-handedly hoists the body of Dr Nat from the basement floor up a couple of feet into the vat.
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: When Colonel Lockjaw goes to the meeting with Throckmorton and Irvine, he combs his hair while in the elevator, but during the meeting, they are messy again. (00:38:50 - 00:39:45)
Deliberate mistake: Concerning the literal "bag drop" off the subway car: The ransom money bag falls from the train directly into the waiting hands of the bad guy, after it falls very arbitrarily from Denzel's hands, after the train is brought very arbitrarily to a screeching halt by another bad guy very arbitrarily hitting the emergency stop. This was sheer fantasy that could never happen in real life even if the thousand unknowns were known. Bigger than a simple plot hole - this was a deliberate mistake.
Continuity mistake: When Abel talks to Louis outside the hospital, the position of Lois's hands - and the cigarette he's holding - changes inconsistently between shots.
