Continuity mistake: The very first scene of the movie the boy rides in on the donkey and has a stick in his right hand he uses to hit the left side of the donkey. The shot changes and another boy yells, "gaka lama lako." and the shot changes to where the camels grunt, notice that the camels, from right to left are as follows in color: beige, beige, white, beige. The shot changes to boys shouting, then the shot changes to the boy about to get off the donkey, but notice the stick in that boy's hand has mysteriously disappeared. The boy gets off the donkey and runs up the platform, and this is where you notice the order of the camels has changed to: beige, beige, beige, white. (00:03:10)
Continuity mistake: In the beginning at the Egyptian temple while speaking to the Priest, the Professor has his cup in his right hand then a brush then the cup again...all while speaking the same sentence. (00:05:35)
Other mistake: In the scene in the beginning when you first see the fifth element, and the camera moves up so you see the wide open mouth, look to the shoulder on the left. In the years of undisturbed dust, there are a few finger prints. (00:09:35)
Continuity mistake: When Billy shouts at the Priest while holding the gun, there is a tripod standing behind Billy to his right. Billy yells, "Don't move." The shot changes to the Priest and then back to Billy again when Billy says, "I have a gun" you notice that the tripod behind him has disappeared. The tripod reappears in the overhead shot where the Priest says, "I'll explain everything." (00:11:00)
Continuity mistake: When the priest is telling Billy to put down the gun, the camera angle from the back shows his left hand making the motion to put the gun down. The camera angle changes to the front and his right hand is now making the motion. (00:11:20)
Continuity mistake: At the beginning of the film, when the door of the tomb is closing on him, the Mondoshawan extends his arm to give the key to the priest. His hand is completely out but the shot later, only the end of his fingers are outside. (00:11:50)
Continuity mistake: When the techs are analyzing the dark planet right before the first attack, the first tech turns to the second to report the sudden drop in surface activity. Between that shot and the following one on the second tech, the first tech's hand jumps from at his side to rising in front of his chin. (00:15:40)
Continuity mistake: During the missile barrage on the dark planet, one of the soldiers says, "The planet has increased in diameter by 200%." That means that the diameter would be triple the original size, but it's obvious from the missile impact animations that it hasn't grown anywhere near that much. (00:16:30)
Continuity mistake: When Korben lets his cat in the apartment, the cat jumps up onto the bed and watches the TV. Korben is then seen dealing with the hoodlum and when he turns to put the gun in the rack, the cat is gone and the bed is back in the wall. (00:19:25 - 00:20:25)
Continuity mistake: When Leeloo is trying to break out of the holding chamber, she bangs her hands against the glass and there is no sign of the tattoos that we see on her wrists when Korben takes her to the priest's house. (00:29:00 - 00:40:55)
Revealing mistake: Right after they "create" Leeloo and she is lying in the plastic cage with the little straps on her, the guy approaches her and says, "if you want out, you are going to have to work on your communication skills." She gives him a dirty look, and then you can see a huge hole, pre-cut in the glass, that she busts her hand through. (00:29:47)
Continuity mistake: When Leeloo jumps from the building, the elevator track, which was attached to the building on her right-hand side, has vanished. (00:30:10)
Other mistake: When Leeloo escapes onto the ledge and goes around the corner of the building, there are people walking across a small bridge. One of these people vanishes in the middle of the bridge when walking to the left. (00:31:20)
Continuity mistake: When LeeLoo is on the ledge outside of the building, the police corner her & take her picture. Her face is pretty calm, but when the picture is developed on the police screen, she looks shocked. (00:32:20)
Continuity mistake: When the police confront Leeloo on the side of the building, she raises her hands and we can see that they're covered in soot. She jumps off and lands in Korben's cab. When she comes to, she presses her hand against the glass, and her hand is magically clean. (00:32:35 - 00:33:20)
Continuity mistake: When Corben bails on the 5-0 (in his taxi with Leeloo), he yanks the police car's winch right out of the car (which resulted in dragging the winch, as well as the entire length of the cable behind his taxi). In the next shot showing his car (4 police cars chasing him down the "street"), the cable and winch have disappeared. (00:36:00)
Continuity mistake: When the cops are are getting the Golden Menus, the girl at the drive-in window hands them their order and you see a multipass on top of one of the boxes. The cop in the passenger seat gives the driver the order and the multipass is gone. (00:36:50)
Continuity mistake: When the police are chasing Korben and Leeloo in the taxi, Korben uses a video display map of "Manhattan 2nd District". When he switches it on, it looks normal, but when the camera cuts away then back again, the display is reversed as though it were in a mirror. (00:37:25)
Other mistake: When the two police officers are searching for Korben's taxi, as one police officer asks "How do they expect us to find anything in this... ", both police officers have the same ID number on their helmets. (00:39:15)
Continuity mistake: When Leeloo is learning English using the Priest's computer, just before David asks him what she's doing, Leeloo is looking at words beginning with "na" (such as "nasty") but as soon as the shot changes she is looking at words beginning with "matt" (such as mattress). Just before she selects "martial arts", she is looking at the following words : master, mastered, mastering and meadow. Firstly, "master" (et al.) all come before mattress in the alphabet, and secondly, mattress (and lots of other words) are between mastering and meadow. (00:46:15)
