The original ad was called "truck", was apparently produced in Shanghai and supposedly launched before any other commercial in that campaign. This is the one that features pop-singer SE7EN, a horrible asian version of THIRD EYE BLIND's "Semi-Charmed Life" -- and is rumored to be directed by David Fincher.
To make things just a little bit more complicated there is a reshoot-version of this exact same ad from 2006, post-produced by Fincher-trusted vfx-house BUF Paris, but reportedly directed by Josh Taft. And this ad belongs to a larger international campaign by SPRITE called "Liquid Freedom", which was launched with a clip from 2005, also directed by Josh Taft and produced by Gang Films (website).
You can find an article on the making of that spot here, and I will post links to all the other commercials at the bottom of this post.
The supposed Fincher connection gets mentioned here, some site named Korean-Bitez (link), Korean Star News (link), and the Trivia section of David Fincher Wikipedia article (link). All I am wondering is -- how did they even get the idea?
To be absolutely fair: The "Liquid Freedom" spot is very well done. I think it's very well directed and has a great concept. Judging by its technical finesse it could even be a Fincher -- but it just doesn't look like a Fincher. Hm?
So if anyone has some more info on his matter and can either confirm or further deny this rumor, please report or comment here. In any other case: Please consider this false news.
