Top 5 Trailers

I'm really dating myself with this one. I'm sure there have been plenty of excellent trailers before these, but these are the ones that I have seen that blew me (and many audiences, I'm sure) away. By the way, does anyone know why they are called "trailers" even though they come before the feature film? ...but I digress. Keep in mind, that this list has nothing to do with how good the movie was, but how good the trailer made it look.
