Miscellaneous:
This film is the first in the franchise that shows a dragon sharing its heart in a new way, as Draco and Drake removed half of theirs and put it through a human's pre-existing wound. Drago shares his heart by getting some of its blood on the claw he uses to cut himself and cutting Gareth's chest with it, leaving a scar. Siveth follows suit in Dragonheart: Vengeance.
It's also the first time a dragon shares its heart with an injured human who's still alive.
It's the first Dragonheart film where multiple dragons share their hearts.
This movie is the first in the Dragonheart series where a dragon bonds with a female human, technically an unborn dragon, but it still counts.
This is the first and only Dragonheart film with a post-credits scene.
