Revealing mistake: The roller coaster used for the Devil's Flight is really the Corkscrew at Playland in Vancouver, where all three movies were filmed. If you look during the opening credits, you can see the name "Corkscrew" up in the lights above the coaster. After this, it says Devil's Flight during the rest of the roller coaster scenes.
Continuity mistake: When the crew is outside and they're going to lock Blair in the tool shed, you can see someone nailing wood across the window on the front of the shed. The pieces of wood are horizontal. In the next shot (inside the shed), if you look at the window in the background, the strips of wood are vertical. When Mac goes back outside, the wood is horizontal again.
Continuity mistake: When Dr. Elliot is doing his presentation, there is a large TV on a stand, with a VCR, which suddenly vanishes halfway through. (00:11:10)
Continuity mistake: During the scene right after Amy's boss drives away, you can see the street behind her, over her shoulder, is empty of vehicles. The camera zooms in as she flicks her cigarette away, and in the cut shot, suddenly a taxi appears over her shoulder, which was not there a second before. (00:37:30)
Visible crew/equipment: When Steven Weber and Kelly Overton find Tom Skerritt's motorcycle in the desert a crew member is visible in the chrome that runs along the red gas tank.
Visible crew/equipment: When Rains wakes up she stands up and shouts "Where is she? What have you done with her?" you can see the camera's shadow moving on her. (00:18:10)
Continuity mistake: When Ro eats the tub of ice cream, the way it faces and the amount in the tub continues to differ.
Visible crew/equipment: When Kevin and Pam are watching the police video of the Moyez raid, as Kevin walks behind Pam, in the wall of windows behind him, you can see the camera man filming and watch him as he swings left to right following Kevin in the shot. (00:30:30)
Continuity mistake: When Rachel begins to brake her car after seeing the deer on the road, as the shots keep changing the markings on the road also keep changing. In overhead shots the markings are a single broken yellow line, but in closeups of the wheels, the markings are solid double yellow lines. (00:30:40)
Continuity mistake: When Stephanie is about to check avionics, Fiona holds the flashlight by the lamp end (bulb) as Stephanie takes the flashlight. However, in the next shot, Fiona still holds the flashlight, but she now holds the other end as Stephanie takes the flashlight from her.
Continuity mistake: When the two villagers throw the slab of meat on the rock for the creatures, it lands rib side up. A second later the meat is shown from a different angle, and now it is lying skin side up. (00:38:05)
Revealing mistake: When the plane first lands at Bangor airport, the words 'American Pride' on the plane are reversed, like they are reflected in a mirror in one shot as its wheels hits the runway. (00:50:55)
Revealing mistake: Near the end of the film when we see Rhodes shoot Larry in the chest, you can see an outline of something underneath his vest, very obviously a device/squib simulating being shot in the chest. (01:15:15)
Continuity mistake: When Bob Conway meets with the High Lama, there is a pillar candle atop a 2 ft tall ornate candle holder, on the table beside the Shangri-La founder. The style of the tall candle holder is actually completely different between the High Lama's side shots and close-up; the height of the wide candle greatly differs as well.
Continuity mistake: While Father Malone is drinking his wine you can still see the cork laying on the table. He finally gets up to try to catch Bennett before he leaves and the cork has mysteriously put itself back into the bottle. (00:05:00 - 00:05:45)
Continuity mistake: Notice the candle on the table in the Italian restaurant scene during Capt. Kirk and Dr. Gillian dialog. It changes height depending who is talking. (01:03:50 - 01:08:30)
Continuity mistake: After Jonathan saves the baby from the car he goes to the funeral. In the funeral he starts talking to the baby's father and while they are talking you see a bald man with glasses pass by and glance at the baby and then in another scene you see the same bald guy pass again. (00:59:30)
Continuity mistake: Look carefully when they transport to the Mexican Restaurant. Her night dress is unbuttoned at the top but mysteriously closes in a matter of seconds.
Continuity mistake: When Memphis is tortured, he gets water poured in his mouth from a bottle. When they're done pouring, the water level in the bottle is almost full. (01:07:00)
Revealing mistake: On each of Sky Captain's hangar doors, the windows are broken in the exact same places, indicating the same window rendering was simply duplicated to make the others. (00:16:45)
Suggested correction: Before this frame, there is a shot showing multiple water bottles on a nearby table... it could easily have been the next bottle of water?
No, it could not because the shot was meant to be continuous. After Memphis spits out the water, we see the guy holding a half filled bottle start pouring water into Memphis' mouth. When the camera angle changes (i.e. continuous shot and not a jump cut), we still see the guy holding the bottle up to Memphis' mouth. It's at that point the bottle has changed and is now almost full.

It's even worse than that. It refills at least twice between those quick successive shots.
