Continuity mistake: During the Venice scenes, Ethan's hair length is always the same, except for scene number 1 where he and the team are on a boat arriving in Venice, and scene number 3 where he and Ilsa are on a balcony. In both these scenes, his hair is very short.

Factual error: Amongst the essential parts of a nuclear weapon's detonation mechanism is a radioactive isotope of tritium, which has a half life of just 12 1/2 years. The tritium in every nuke on earth has to be replaced every ten years or so. This is by no means unusual; there are other perishable parts including detonators made of conventional explosives which would be completely inert after a thousand years. After lying dormant with no maintenance at all for that amount of time the nuclear weapons the 'Man-animals' find would be big shiny paperweights and not much else.

Revealing mistake: During the Miss United States Pageant, there are close-up shots of the audience and it is very obvious that in the balcony and back part of the audience, especially when seeing the 'men' with bow ties, they are fake - mostly cardboard cut outs. (01:22:50)

Revealing mistake: When Elly is "skating" on the black oil while fighting the bad guys, we can see that it is Bryce Dallas Howard's stunt double in a few shots where it briefly shows her face.

Sissy: You a real cowboy?
Bud: Well that depends on what you think a real cowboy is?
Sissy: Know how to do 2-step?
Bud: You bet.
Sissy: Wanna prove it?

Trivia: In the last scene, when everyone meets to play poker, Catherine Zeta Jones throws her hands up to celebrate a win and falls out of her chair for real.

Continuity mistake: During the street chase in Brazil, the time of day changes from night, to perhaps late afternoon/evening, to night again.

Continuity mistake: At Skull Rock, after the crocodile has nipped off a good bit of Hook's clothing, sock and shoe, when Hook rushes toward Smee in the boat the crocodile opens his mouth, and just as he swallows Hook he's nearly fully clothed and wearing both socks and both shoes.

Factual error: When the fish tank has been cleaned by the newly installed laser fish cleaner, the machine states that the water temperature is '82°.' In Australia the Celsius scale is used; therefore, it should be about '28°.' Australia is 100% metric and has been since 1974! Nobody in Australia - nobody, anywhere, any time since 1974, uses imperial measures. There is absolutely no question of the dentist having an imperial thermometer or expressing himself in° Fahrenheit. It is actually illegal to import or sell any instrument using 'Imperial' scales. You couldn't buy a Fahrenheit thermometer if you tried. (01:14:30)

Question: During the end credits it says "Dedicated to Ryan Mone." Who was he and what happened to this man?

Revealing mistake: When Amidala and Anakin are eating and he cuts her a piece of the fruit and "floats" it back to her, the bite appears in the fruit a split second before she actually eats it. [This appears to be fixed in rereleased versions]. (00:53:40)
