Other mistake: In the end credits, BASSES is misspelled as BASESS. (01:45:10)
Other mistake: In the DVD bonus feature "Science Behind the Fiction", director Paul McGuigan describes says he typed "psychic powers experiments" into a search engine. This is illustrated with a computer display on which the text being typed reads "pychic powers experiments."
Answer: Soy sauce is mostly soy protein and salt in water- it might raise your blood pressure for a while, but assuming you're in reasonably good health, and presuming it wasn't a ridiculously large amount, your liver will filter it out after a short while.
This is incorrect, there are several variables in this but given the syringe size I'm guessing that he injected approx 50ml. Now 50ml injected intravenously would almost certainly cause sepsis and he would die from septic shock within a day or so. The reason for this is that soy sauce is a fermented product full of several different types of bacteria in large quantities which would be quite friendly in the gut but disastrous in the blood stream. Also the sodium and yeasts and funghi in the sauce would not be good either. If however the injection was subcutaneous but not intravenous then it may not be fatal but it would certainly give him a very nasty infected cyst that would have the potential to be fatal if not treated correctly.
