Honda 'live every litre' by Grey London

Honda is launching an online trailer to promote a crowd-sourced documentary film, devised by Grey London, to promote the new Honda CR-Z.

The film was preceded by a social media campaign which invited people to submit their dream journeys to the website

Users then voted for 13 people whose trips would be filmed by the director Claudio Von Plata.

The final documentary film features five participants, including three men who attempt to cross Lake Garda in Italy on a bouncy castle.

The film will premiere at a London event and online on 21 July, followed by further launches in major European cities.
