From the film-maker:
I don’t think that dragons are evil creatures. Quite the opposite actually: dragons are wise and gentle, or most likely, they just live their own life. This had always bothered me, but this time I had the chance to let the truth shine, to explain that dragons are abused and killed by evil knights!
So my initial idea was to show a well-mannered dragon happily minding his business in his own den: making himself a vegetarian broccoli soup (because he’s so gentle that he would never kill anyone, not even to feed himself). All of a sudden the quiet is broken by a rude knight dragging around a poor and helpless princess. The dragon tries to save her from her miserable destiny, only to be killed by the evil and cowardly knight.
Originally I thought that it would be nice to use this story as a metaphor to represent domestic violence: that often violence is most likely to come from people you know rather than from strangers.
A piece inspired by Paolo Uccello: Saint George and the Dragon, about 1470
