Revealing mistake: Whilst in Q's workshop, Bond places his envelope on Q's X-Ray Document scanner. If you pay close attention to the screen (it's easy to notice anyway) his flight ticket has got VOID written on it 4 times... (00:51:54)
Revealing mistake: When Fred rushes in to fight the Black Knight Ghost in Mr. Wickles' castle, he is hit in the face several times with the back of his shield. As he falls, you can see the pad on the back of the shield to protect his face. (It is not noticeable when he first runs in.) (00:23:20)
Continuity mistake: The guard sitting on the back of the train has sweat covering the front of his shirt. In the next shot, the sweat is gone.
Visible crew/equipment: During Bud and Coffey's fight in the lab, we see a lightbulb swinging from side to side between the two men. If you look closely, you can see a hand (belonging to a third person) pushing the lightbulb. The only people in the room are Bud and Coffey. (01:44:16)
Revealing mistake: When Jason climbs onto the rail of the fire escape, it is not attached to the wall - intentionally, it has not broken - but then in another shot, two seconds later, it 'breaks'. It pulls out of a visible hole in the wall, although it was never actually attached and there was no hole before. (00:23:25)
Continuity mistake: When the Angels are walking through the sprinklers after getting shot, you can see the bullet holes in each one of the Angels' shirts. When they get to the car, and it blows up, Cameron Diaz's bullet hole disappears. (01:20:00 - 01:21:30)
Visible crew/equipment: When Duane hits the second cow while hanging from the rope, if you watch carefully you can see the head of someone, bent down behind the cow, wearing a white hat. (01:01:30)
Revealing mistake: In the subway scene, when Neo gets slammed towards the wall (and crashes into it) it's visibly Keanu's stunt double.
Visible crew/equipment: Before the last battle, when the Wendol warlord nears the Norse village he's on horseback and raises his arm swinging his weapon. It cuts to his closeup, and under his right arm there's a visible plastic slider buckle on the strap (looks like nylon) of his bear costume. (01:21:15 - 01:30:55)
Continuity mistake: When doctors are discussing the medical condition of Dave Bowman's mother, a close-up of the African-American doctor shows a framed newspaper on the wall behind him. It is the front page and has prominent pictures of Bowman and Poole taken during their mission. In the next, wider shot, we see this wall suddenly has nothing on it - the newspaper and frame have vanished. They return when Bowman's mother sits up in bed. (01:16:45)
Continuity mistake: After trying to entice the primitive tribe with flashy clothes and a boom box, Alvin and Simon get tied to a hut. The four ropes around their wrists are initially tied together in one knot right above their heads. But once they notice that Theodore is being pampered like a god, Alvin and Simon's wrist ropes are suddenly knotted separately instead. (00:51:05)
Visible crew/equipment: When Jake is on the medevac helicopter headed to Billie and Little, you can see the film crew in the bottom left of the screen, before it lands (this is not visible in the widescreen version). (01:18:00)
Revealing mistake: When Jimmy attempts to kill himself, the bullet hole on his back is far above where he shot himself in the chest. At least 4-6 inches higher, AND the gun was slanted downward.
Continuity mistake: After receiving the phone call from Nancy, when Robert and Morgan are talking in the taxi, his seatbelt repeatedly changes from over to under his trench coat collar. (00:16:45)
Visible crew/equipment: During the jungle chase, Marion jumps out of the truck, leaving Dovchenko driverless. A few shots later, Spalko fires on the two amphibious vehicles, and when Mac removes his cap to check his head, the actor's modern wired device (earbud or mic perhaps) drops out from under his scarf/shirt and hangs over his shirt. Later, in the chamber with the crystal skeletons, Mac admits to lying about the CIA, then as Spalko climbs the chamber stairs, it looks like her lav mic is a bit visible between two upper buttons. (01:17:10 - 01:44:15)
Continuity mistake: When Garfield is in outer space asking the computer to tell him if he's really living in life number 9, his armchair vanishes for an entire shot. (00:40:00)
Continuity mistake: Optimus and the car Tessa is trapped in are caught in a net and are pulled up to Lockdown's ship. Cade then jumps and grabs onto the net whilst it is being raised. There is a brief moment where Optimus is not visible inside the from the net, before being visible again in the next shot. The CG artists likely forgot to add Optimus into the shot during post-production. (01:22:35)
Visible crew/equipment: After Doctor Strange experiments with the magical doorway in the Sanctum Sanctorum, he leaves it on a desert view and we cut to a shot panning across all the artifacts. At the very start of the shot on the right hand side of the screen is a crewmember standing in the shadows looking bored. Really blatant if you turn up the brightness, but easy enough to spot if you know what you're looking at. (00:56:00)
Continuity mistake: When Moana is throwing sticks into the ground, after she starts singing, look back at that spot and all the thrown sticks have disappeared.
Continuity mistake: Right in the beginning, Wade hops out a window from his home and starts walking beside it to the edge to climb to the next level down. As he starts walking he passes by another window with a curtain. It then cuts to a closer angle and suddenly the window no longer has a curtain. Also a wire appears on the wall in front of him. And you can tell it is the same house, not a time jump, as the rust at the top of the window frame is exactly the same. (00:01:15)
