Thomas Gabriel: [Probing a gunshot wound in McClane's shoulder with his gun.] On your tombstone, it should say "Always at the wrong place at the wrong time."
John McClane: How about... [grunts.] Yippee-ki-yay... Motherfucker! [Grabs the gun and fires it through himself and into Gabriel.].
When John and Mai are fighting at the power plant, John tosses Mai up against a glass board. Her pony tail has come undone and her hair is a big mess. You see Mai from the back as she gets up to come after John. Her hair is now neatly combed and back in a pony tail. But as she begins to fight, her hair is once again undone and messy.
The film's title is a reference to New Hampshire's state motto "Live Free or Die." The film was shipped to theaters under the title "New Hampshire."
