I've seen the trailers for World War Z countless times, and for the longest time I was all like "what the heck? What, do they expect us to believe that only Brad Pitt and his family get saved out of everyone wanting on the helicopter? That's stupid! I don't even know what's going on!"
I realized it about halfway through the trailer for it before MoS that the Z stands for Zombie!
