This is a teaser trailer which was designed to build hype surrounding Ireland Bound. Most specifically the social media aspects concerning it. As the documentary was being filmed the person involved was blogging and tweeting about their experiences abroad as they moved about the country.
The ultimate joke about this trailer was that we could not find a green wall that was the right color we were looking for so as a work around we filmed the whole thing in front of a green screen and chromakeyed in the appropriate green in post. You really can fix anything in post.
