Here's a more long form prompt:
Tell the story of a movie as though it were a fairytale. And yes, Disney movies based on fairytales are cheating. You can change any element of the plot to better match up with the style of a fairytale, as long as the basic plot is recognizable.
For example, the tale of a fantastical land where dragons roam and one knight's quest to keep them from escaping. (Jurassic Park)
