Now take a really close look between the eyes of the skull and you can see this distinctly alien-looking figure:
It's either an alien, or a pumpkin.
Well ain't that something? Over a year before the movie actually came out, the film's marketing group must have been trying to secretly warn us not to see it because it's a fucking Indiana Jones movie with goddamn aliens in it.
And while the Cloverfield marketing blitz was full of secret codes, alternate-reality games and strange, unwashed people combing every frame of every trailer, it still took people over a year after the movie's release to notice that there's apparently a very well-hidden image of the Monster in the poster.
