Continuity mistake: When Paul comes to the table three chairs are free, when his father comes there is only one chair free - the third chair is suddenly missing. (00:49:30)

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.

Visible crew/equipment: After escaping the T. Rex, when Alan and the kids climb the huge tree we can see a bit of what looks like netting at the top right side of the screen and also the set's scaffolding at the left side, then after the scene with Hammond and Ellie in the dining hall, when it cuts back to Alan and the kids we can see much more of the netting behind the tree set, at the top of the screen.

Trivia: Writer/director Marc Lawrence went to Binghamton University.

Continuity mistake: In the final scene when Stark, Rhodes and the senator have a picture taken, Tony's jacket is first buttoned, then unbuttoned from the same viewing angle. (01:56:50)

Question: Several other answers and corrections state that the reddish liquid sprayed by the tripods was what essentially grew the red vines. However I thought I heard someone in the film say something along the lines of "using us (i.e. blood) as fertiliser". Can someone please clarify?

Trivia: During the opening fight scene, Comedian throws a mug at his attacker, but misses. The mug strikes the numerals on his apartment door, knocking the '1' off. This turns 3001 into "300", the name of the director's previous hit film.

Robin Hood: For my first order of business, I wish to appoint a new Sheriff of Rottingham. My friend, Achoo.
Achoo: All right.
Crowd: A black sheriff?
Blinkin: He's black?
Achoo: And why not? It worked in Blazing Saddles.

Continuity mistake: In the beginning scenes, where Milo Thatch is practising his proposal, he slides over (face forward, chest against the board) a chalk drawing of a map detailing the location of Atlantis. When he realises he wiped off the drawing, and sees it on his clothes, he stands in front of the blank part of the chalkboard, "filling in" the space with the map that rubbed off on his shirt - the only problem is, that the image should have rubbed off backwards as he was facing the board when it transferred to his clothes. He could not simply stand in the place of the missing map face forward and have it read properly.

Other mistake: Before Uncle Owen yells for Luke, if you look very closely, a fly can be seen on the lens (best seen on the special edition release). The fly was removed in the 2019 release.

Other mistake: After the first race, in the scene where Lightning is rushing out on the stage thinking he is the winner, loads of confetti is shot out when the King and Chick Hicks gets onto the stage. The confetti is then falling down, but not a single flake hits any of the cars. However, in the following shots, you can see plenty of it on the stage underneath the cars, even though they haven't moved.
