Without looking it up on the web, when I quote from the following description, from Time magazine, of a new movie, how many of you recognize the original short story and know the author, before the first sentence is finished?

( some spoilers here, based on the movie's web site )

Oh yeah, and what kind of a name is Rainn? Does he have a sister named Sunnshinne?
