After watching the countdown on operationearlybird.com hit zero, and refreshing my page, scratching my head, I have finally figured out what it is (I think). The page shows a map, on that map there are points, after a click the points will turn green, find the location that represents your location, and it will let you get tickets to an early screening of the prologue.

You are invited to a special advance screening of The Dark Knight Rises - Prologue

Head over to the site and get your tickets while you can !
