Continuity mistake: Following Rodney's step from the escalator on the red pedestal he is being scooped into one half of a wire-frame globe/ball. Two halves now (the other one has Fender in it) form an intact globe. A safety bar with a 'wooden' middle bit (like those on rollercoasters) suddenly appears. After their journey, when the ball splits back into two halves, the safety bar, which previously had mysteriously appeared, now has disappeared.
Continuity mistake: The plane they are on changes several times throughout the movie. When it is sitting at the gate in Dallas, and while being pushed back from the gate, it is a Boeing 737. When it is shown taxiing out, it is an Airbus A320. Air to air shots are of a Boeing 767, which is also the same as the interior shots all throughout the movie. The 737 and A320 are narrowbodies, while the 767 is a widebody, commonly configured 2-4-2 like the interior in the movie.

Continuity mistake: When Bruce is thrown off the truck when released from prison, you can see his bag in the background as he rolls at least 5 feet away to his right. When the angle changes and he's getting up, the bag is right in front of him, if not slightly to his left. (00:05:50)
Continuity mistake: When the cast are at the Miranda colony and discover that everyone is dead, there is a rotating shot of River as she realises what happened. Prior to this there is a brief closeup shot of the rest of the cast as they turn to face her. Jayne turns to his right, but in the following rotating shot of River he has turned from his left. (01:16:30)

Continuity mistake: The chain saw on the block of ice switches ice blocks more than once.
Continuity mistake: The male lead is seen reading an article in the newspaper, the headline of which says "serial killer arrested at Pendleton University," but when he reads the headline aloud, he mentions the professor that killed students at Alpine University, which doesn't match the headline from the paper he's reading.
Deliberate mistake: When the New York subway is flooded the interior shot shows the station is Wilshire Blvd. Wilshire Blvd is in Los Angeles and the film clip appears to be stock footage from the Universal Studios Tour ride.
Audio problem: In the scene where Todd and Jeremy are in the bedroom together and Todd is lying on top of Jeremy asking to play "tummysticks", - right before Sen Clary is about to come in and Jeremy begins to panic, watch Jeremy as he's lying on the bed talking.

But during the scene it continues to swap to an angle behind the two shakers - but now the cereal box and milk carton have vanished, so as not to block the view for this angled shot. (00:12:30)
Plot hole: At the beginning, it shows Santiago crossing the border into the U.S. But the U.S. border patrol is on the Mexican side.
Factual error: In the fire at the lighthouse, Stevie puts her hand on the fire extinguisher nozzle. It would have frozen her hand and made it stick to it.
Factual error: A very common error in First World War films. British soldiers were not permitted to shave their upper lips until 1916 - in 1914 almost all (unless physically unable to grow them) would have had moustaches.
