At least!

Beer ad viral campaign a hit
"Shot by an Academy Award-winning cinematographer and co-produced by Australian special-effects wizards Animal Logic, who worked on The Matrix trilogy, the Carlton Draught Big Ad took months to complete and is of epic proportions.
Reminiscent of a series of British Airways ads, an aerial shot reveals the two groups of men coming together to form a gigantic image of a man drinking a schooner of beer.
Created by the George Patterson Partners agency, the ad was shot in New Zealand and featured 300 actors and more than 20,000 computer-generated men.
Brewer CUB attributes Carlton Draught's recent sales surge to marketing which parodies traditional beer advertising. "

It is fun-ny.
So ve-ry fun-y.
One of the fun-i-eeeeessssst!

(I've been talking like this all day.)

Maybe he kept the strange spelling in order to be exotic. "Johan" is after all as common as "John". But where they got the idea he was Austrian, I don't know. *shrug*
