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.
Continuity mistake: After the pool incident when David is writing letters. Monica is looking over the letters that David has written. There's a point where you can see that she's still holding at least 2-3 sheets of paper but when the camera shifts back to the writing there's only one in her hand. There should be more than one paper in her hand. And when viewed from behind her back the sheets are neatly lying on top of each other, when seen from the front, the sheets are tilted. (00:46:43)
Continuity mistake: During the fight with Gabe and Yulaw, Yulaw does a powerful move of lunging forward and smashing Gabe with both his fists, sending him flying into a green metal box that crumbles from the impact. Gabe then falls to the floor, close to the box. The shot changes to Yulaw thinking he has victory, then back to Gabe. Gabe is now noticeably further from the green box, and his arms and legs are in different positions. (01:08:40)
Continuity mistake: When Juni handcuffs the metal box to his wrist, it switches back forth from his right wrist to his left over and over again. (00:35:05)
Continuity mistake: During the scene in the mall when the girl is in the dressing room, she keeps putting on more layers of clothing.

Continuity mistake: When Thade takes the weapon from Leo the weapon is a futuristic laser type gun. When Thade is firing the weapon after being locked in the command centre, the gun is a stainless steel Beretta brigadier model. (01:50:00)
Continuity mistake: In the scene where Dr. Grant gets rescued by the kid and they are sitting in the water tank (truck) eating candy bars they show the kid eating a "Crunch" bar with no wrapper, just in the tin foil. In the next shot you see him eating the same candy bar but the "Crunch" wrapper is now on, then in the third shot it cuts back to the kid and the wrapper is gone and you only see tin foil again. (00:46:40)
Continuity mistake: When Charlie and Leopold are walking home after they go to the bar, Leopold says it is after midnight and they should go home. The next scene is back at the restaurant with Kate and J.J. When the camera is on J.J., you can see his watch and it says it's 9:30. (00:57:00)
Continuity mistake: When Cherita makes her mark on the lifeline blackboard, there are some smudges on the broad chalk line. In the next shot, the line is perfect again. (00:41:30)
Continuity mistake: When the panel of doctors are being queried by Aames, for the second time of the loop of this interview, the black box containing the mask can clearly be seen in the bottom right hand corner on the desk when the camera swings to the main doctor. When the camera pans back again, it is gone, and it is only after this that the assistant brings in the box.

Continuity mistake: When Remy falls through the barricade she is wearing a G-string, but when she strips down to mix up the scent she is wearing different underwear.
Continuity mistake: Right after Aki saves Gray and turns around to pick up the canister containing the plant off a table there is no table or ledge. If you watch the movie with the commentary one of the members involved with the movie says that it is floating on nothing. (00:16:50)
