Hummer gets into the holiday swing with a new commercial directed by Independent Media's Kathryn Bigelow. The spot, from Boston's Modernista!, shows a father and two sons as they jet down a mountain on a runaway sled to a soundtrack borrowed from How the Grinch Stole Christmas
. As the the wild ride wears on, we follow their tracks back up the mountain and see how they got up there in the first place -- in a Hummer H2, of course. The Mill provided the visual effects while Boston's Brickyard contributed effects and the Seussian end graphics.
