The makers of the Nazi zombie film Dead Snow commissioned this viral marketing campaign to promote the Norwegian DVD (and concurrent US theatrical release). Curiously, the above video doesn't feature any Nazis, zombies, or even snow. Just a bunch of not-safe-for-work hot chicks jiggling to an inane Europop song. Genius.
For the record, I was intent on checking out this movie well before I saw this video. It did not affect my opinion. At all.
