I don't care enough to watch the old ones and check, but I think this is new, international trailer for Knowing. Even if it's not, this is a good chance to re-watch and try to figure out what the big reveal at the end is going to be. We know the series of seemingly-random numbers some girl wrote in 50-year-old time capsule predict the dates of future disasters, but HOW!? And what is Nicolas Cage going to do about it!? I'm guessing he somehow sacrifices himself to make the numbers not add up, thus saving Earth. Then we flash back to 1958 and see the girl scratching out the last date, and we all breathe a sigh of relief, but then she writes a new disaster date that's set for like 2012, and we're like, "Shit, sequel!" Or maybe it's just ghosts or aliens or something.
