Deliberate mistake: When Tarzan fights with the leopard, it scratches his chest. However after they fall into the pit and Tarzan comes out carrying the dead leopard, the scratches on his chest have amazingly healed. [It is a long-standing Disney tradition that no evidence of violence is shown on screen. Still a mistake, but there's why].
Deliberate mistake: When Neo and Morpheus are in the construct place (where it is all white), you can see that Morpheus' glasses are a matte grey and then a second later they are totally reflective. [The shot where Morpheus has flat black glasses was shot with a steadycam. A cameraman using a special camera strapped to his body walks in a snaking path from behind Neo, to behind Morpheus. He passes in front of Morpheus at least once. His glasses were painted flat black to prevent the reflection of the steadycam operator showing up on film. At the end of the shot, you can see the back side of the lens. While doing this scene and saying his dialogue, Laurence Fishburne couldn't see anything.] (00:38:10)
Deliberate mistake: When Commander Taggert and Lt. Madison are about to press the blue button to stop the ship exploding, Lt. Madison's tunic is mostly zipped up. A few seconds later it is suddenly mostly unzipped. Those of you who have access to the DVD of the film can see that there was a deleted scene which was originally intended to go in here where she unzips her tunic to distract the aliens.
Deliberate mistake: When Austin and Felicity cross the street when they are shopping, you can see green hills behind them, very much like Hollywood and not 1969 London. (Deliberate reference to an earlier joke)
Deliberate mistake: When Jar Jar gets arrested in the Gungan city, in the second shot of Jar Jar and Obi-Wan, Obi-Wan and a part of the floor behind him are reversed. This can be seen, for example, because two of the red areas on the floor have switched positions, and Obi-Wan's braid and lightsaber are on the wrong side. (00:14:00)
Deliberate mistake: Even though Hamm is flicking through the channels at the same speed, the side with Al's advert on it is visible for longer.
Deliberate mistake: The shot of Ardeth and his companions watching Rick leave Hamunuptra at the start of the film is reused again when Rick, Evie, Jonathan and the Warden re-enter Hamunuptra, although the reused shot has a blue filter over it. Ardeth even says exactly the same line he says in the original shot, but it is subtitled differently.
Deliberate mistake: The currency conversion program Bond uses to convert GBP into USD only has fields for a 7 figure amount. That's rather small for an organisation like MI6.
