Most unrealistic throat-cutting ever (spoiler)
I've only seen the R-rated version, but the special effects in that scene are terrible. Who reaches for a gaping neck wound with clenched fists?! Hardy's hands are clearing holding blood bags or a bloody sponge or something when he reaches for his neck... with his fingers clenched. Then he squeezes his hands and blood oozes from between his fingers, opening his hands once they're actually on his neck, and then WIPES HIS HANDS on his neck awkwardly to make it look more bloody. A fall to the floor, again with clenched fists hiding blood bags, and we once again see him squeezing his fingers so the blood runs between his fingers. WTH?
Die Hard 2 did a far more convincing throat-cutting - in 1990.
