Corrected entry: An electromagnet is used to pull a metal lever on the other side of a metal door. The metal door would shield the lever, making this impossible.
Corrected entry: It is the height of insanity that the underground laboratory does not have an emergency exit; even a top secret government facility would have one. This lab handles highly inflammable and explosive substances and would have a clear and well rehearsed evacuation procedure. Having said that, at the end of the film the survivors of Sebastian's rampage simply open the roof hatch of the lift and climb the ladder that is on one side of the lift shaft. Why didn't they all do that in the first place? Beats getting killed by an invisible, overacting psychotic.
Correction: Why didn't they do that in the first place? What, and leave an invisible overacting psychotic alone down there, all ready to escape and wreak havoc on the world? Yeah, that would be sensible. They stay down there to try to correct the huge mistake that they made, either by talking Sebastian down and curing him or, once that proves to be a non-option, by killing him. They're attempting to take responsibility for their actions - the fact that it doesn't work, leaving them at his mercy, doesn't make their initial decision a mistake.
They were perfectly fine leaving in the beginning :D also just take the glasses climb up, wait for him upstairs to show up and neutralize him since there is only one exit.
Corrected entry: After making Kevin's mask, Elizabeth Shue cuts circles around his eyes by using a scissors, but the circles weren't that perfect. In the next shots, until the end of the movie, they became flawless.
Correction: The next shots of him wearing the mask are several days later (He was shifted for three days, they failed at bringing him back, made the mask and the next time we see him he says he's been shifted for ten days). There's been plenty of time for them to be making fine adjustments to the mask, or for that matter, make more masks.
Corrected entry: Sebastian can see perfectly like anyone else but because he's invisible light would hit his retinas from all directions making him effectively blind.
Correction: According to the movie, the serum "quantum shifts" the user out of other visual light ranges. It puts him out of phase with the people around him. The light isn't passing through him, he is just out of phase with the light.
Corrected entry: When locked in the freezer, why didn't Linda simply yank out a few of the obvious hanging wires behind the refrigeration unit?
Correction: Even if she did do this, given that she's in an airtight refrigeration unit, she'd still be suffering from the cold for a long time. It makes sense that she'd try to figure out a way to escape rather than wasting time tearing out wires.
Corrected entry: Kevin Bacon shouldn't be able to see anything - the cornea refracts light rays to the back of the eyeball to the optic nerve, a central point. If the cornea was invisible, light rays would go straight out the back of his head and he would have no vision.
Correction: The serum "quantum shifts" the user out of others visual light ranges. It puts him out of phase with the people around him. The light isn't passing through him, he is just out of phase with the light.
Corrected entry: When we see Sebastian's saucy neighbour for the first time, she has blinds on the window, but when Sebastian is invisible and he looks at her again, she has curtains.
Correction: Not a mistake, she could have easily changed it herself.
Corrected entry: In the scene where Kevin Bacon is injecting himself with the invisibility serum, you can see that there is air in the tube, and it is injected into his vein. It is lethal to have air in your veins, so he would die within seconds.
Correction: Urban myth, not medical fact. A small amount of air will dissolve perfectly adequately in the bloodstream, and in fact you'd need about 1500cc of air to form a fatal embolism.
Corrected entry: After Sebastian turns invisible, the first thing he complains about is the lights being too bright. The team explains it away by pointing out that his eyelids are transparent, so his eyes are now extremely sensitive to light. However, over the next few scenes, the lights are as bright as before. When Sebastian is complaining to Elisabeth Shue about his condition, he reaches over and turns on a lamp. His face and eyes are pointed directly at the lamp, but it no longer affects him.
Correction: When in the dark for a long time and then subjected to light, the first thing most people do is shield their eyes. Then, over a few moments, they can begin to open their eyes, because their eyes adjust. This is what his eyes did, they adjusted.
Corrected entry: Since the freezer Elizabeth Shue and her boyfriend are locked into have temperatures both ways, why doesn't she just push it up to +50 degrees?
Correction: The Temperature control dial is on the outside of the chiller and it is unlikly it was built with a second dial on the inside as there would be no need for it.
Corrected entry: Before Sebastian tries to escape, he makes nitro-glycerine, but the way he uses isn't real. He mixes sulphuric acid with other compounds, but the REAL way is mixing sulphuric and nitric acids with glycerine on a ice bath (because Nitro-glycerine detonates at 30 ºC in presence of nitric acid), and the extracting the nitro-glycerine from the acid. Nitro-glycerine is clear-orange, but there has a strange brown colour.
Correction: If you were a movie maker, would you show millions of people the correct way to easily make a powerful explosive?
Correction: Not so. The door is typically made of stainless steel for this type of environment, durable and easy to clean. And also; not magnetic.
