It's fascinating to see how each Hollywood movie vying for blockbuster status handles its marketing campaign. Some decide that showing the entire movie in the trailer is no big deal, others tend to just tease out details. And then there's 'Paranormal Activity 2', which has decided to kick things up a notch by releasing a trailer that you actually have to tease details out of.

The first trailer Paramount put out seemed like a normal teaser trailer that offered a fairly straightforward sampling of what new director Tod Williams and screenwriter Michael Perry have in store for returning fans of the first film. But when some eagle eyed viewers examined the images in said trailer they started to notice it wasn't quite so straightforward: one could find warning signs written on the bedroom mirror and, at one point, the mirror was reflecting the image of a baby that wasn't actually in the room. Well the cryptic brand of spookiness has continued with a new trailer.
