Hehehe. Spoilers.
For a movie based off books written decades ago?
It occurs to me though if you have a girl you are tyring to impress you could take her on opening night and tell her how you were involved in the making of the movie. Tell her you were assistant producer or something. If she doesn't believe you, which she wont cause you are probably a total dork, you can "prove" it by telling her what's gonna happen in the next scene.
