Neil Gaiman a écrit un papier pour le journal The Guardian dans lequel il explique comment lui est venu l'idée de Stardust, à quelques jours de la sortie de l'adaptation au ciné.
Petit extrait :
I started writing Stardust in 1994, but mentally timeslipped about 70 years to do it. The mid-1920s seemed like a time when people enjoyed writing those sorts of things, before there were fantasy shelves in the bookshops, before trilogies and books "in the great tradition of The Lord of the Rings". This, on the other hand, would be in the tradition of Lud-in-the-Mist and The King of Elfland's Daughter. All I was certain of was that nobody had written books on computers back in the 1920s, so I bought a large book of unlined pages, the first fountain pen I had owned since my schooldays and a copy of Katharine Briggs' Dictionary of Fairies. I filled the pen and began.
I wanted a young man who would set out on a quest - in this case a romantic quest, for the heart of Victoria Forester, the loveliest girl in his village. The village was somewhere in England, and was called Wall, after the wall that runs beside it, a dull-looking wall in a normal-looking meadow. And on the other side of the wall was Faerie - Faerie as a place or as a quality, rather than as a posh way of spelling fairy. Our hero would promise to bring back a fallen star, one that had fallen on the far side of the wall.
And the star, I knew, would not, when he found it, be a lump of metallic rock. It would be a young woman with a broken leg, in a poor temper, with no desire to be dragged halfway across the world and presented to anyone's girlfriend.
On the way, we would encounter wicked witches, who would seek the star's heart to give back their youth, and seven lords (some living, some ghosts) who seek the star to confirm their inheritance. There would be obstacles of all kinds, and assistance from odd quarters. And the hero would win through, in the manner of heroes, not because he was especially wise or strong or brave, but because he had a good heart, and because it was his story."
