Jumping the gun

Rebecca Serle's upcoming Romeo and Juliet spin-off When You Were Mine isn't out until next May, but Vulture informs me there's already a film adaptation in the works. (The novel is a revisionist take on Shakespeare's story focused on Rosaline, Romeo's immediately-prior-to-Juliet love interest.) It's a little mind-boggling to consider that Hollywood is so gung-ho over a a debut novel, but apparently they're confident enough to get the ball rolling early: the production crew is already in place, Kiera Knightley is rumored to star, and the film may well be done before the novel is released.
