I hate the fact that movie promotion these days consists of hundreds of "viral" marketing pieces and thousands of teaser trailers. I pretty much avoided the internet for 3 months before the latest Batman movie came out so it wasn't ruined for me. I much preferred it when we got one trailer and a poster then got to actually watch the movie.
Having said that, this "official trailer #3" for Looper is one of the coolest pieces of movie promo I've seen in ages. The whole thing was made using the artwork of Zachary Johnson, who then worked with Noah Fisher to animate it.
