A very clever and creative piece of advertising/awareness raising for Transport For London. It was created by agency WCRS and directed by Chris Palmer at Gorgeous Films, who also did this similar TFL film a while ago.

I just wonder if there shouldn’t have been more of a digital side to the campaign. Some kind of interactive quiz or game element that allows people to pass on the film without actually giving away the answer. Something that builds up over time. There is a website for the campaign, but it doesn’t really add that much, does it. 
Still, very enjoyable piece of communication.
