Factual error: Immediately after Eddie surfaces following his dive, he rests with his head well above the water. Had he actually been in water deep enough for the dive, he would have floated with his chin about even with the surface.
Factual error: During the shootout in the apartment, the blinded henchman fires his handgun 24 times before reloading (and about the same afterwards). Only small-calibre pistols would have that capacity, and the gun he's using isn't one (either to look at and from the bullet holes it causes).Jon Sandys
Factual error: Eddie claims it takes 30s for the drug to take effect. Tablets/capsules do not work within 30 seconds after ingestion. At most, 15mins is the time a drug can be absorbed into the body. This is also noted in the movie reviews.
