Corrected entry: The shot which follows on immediately after Dollarhyde is shot shows a large stain of blood under him in the shape of a dragon's wings. He could not have lost that much blood that quickly, and it would be impossible for it to form so accurate a shape that fast.
Corrected entry: Francis Dolarhyde's name is spelled with one l, but on the driver's license displayed in the film, it is spelled with two.
Correction: This is a discrepancy between the movie and the "Red Dragon" novel, not a mistake within the movie.
Correction: If one of the bullets penetrated the aorta, Dallarhyde would bleed out within seconds. Literally. Impossible to form that shape? Why? Is there some sort of restriction on this kind of thing? Unlikely, maybe, impossible, no.
