After the "perfect being"(Leeloo) has been recronstructed, notice the glass chamber just before she punches her fist through it. It is already broken. It helps to play in slow-motion.
I noticed this too, and it was not in slow mo. It was in the normal speed mode on an old tv, running from free tv. This even becomes more obvious at an Electrical retail super store, on a super flat LCD wide-screen that costs $20,000 australian running this film on a professional surround system DVD. I saw this slip-up today for the second time at that superstore, hence the reason why I came here, just incase this mistake was not posted before. What makes this slip-up so bad is the fact that it is so obvious, you do not need to slow it down, and you only need decent eyes to spot it. Just look at the spot where the created 5th element is about to punch, and will see for about 1/3 of a second the marks of the 'allready' broken glass, just before her fist goes through. I even rewinded the DVD a little to have a better laugh. lol.
I saw it too. But I don't think it was already broken. By the looks of it, part of the glass has been cut with a glass cutter to make it smash more "nicely" (round)
Actually, they don't use real glass, because obviously it could cut someone when they broke it. They use a substance that is called "Candy Glass." I'm not sure EXACTLY how it is made, but I understand that you have to bake it at a certain temperature and it is much like plastic.. In fact, it's very similar to a Jolly Rancher and can be dyed many different colors. This is used in many movies and is most often seen as a window or a beer bottle that is smashed over someone's head. Normally it breaks very easily. but if I had to guess, I'd say they made it a little too thick or they overcooked it (which could make it too hard) and had to cut it so that LeeLoo could break it more easily.
The glass they use, or at least used to, I don't know if they still use it or made something better/safer, is actually made of sugar. and I think the reason it was cut was actually because only that secion of the glass was fake, the rest was normal glass or something else cause if you notice, the cut is kinda jagged but when you see the hole, it's almost perfectly round. they probably did that cause if the whole thing was candy glass, more than just that could break and that would be dangerous cause sugar or not, it's still glass-like.
