When actor Christopher Walken trained as a music-theater dancer, he surely couldn’t have imagined that he’d one day be putting his delicate skills to use at an L.A. hotel on behalf of a British DJ and musician. But that’s exactly what went down, thanks to Spike Jonze, who rented out a Marriott and instructed Walken to dance and fly around the building. If you’re wondering what Fatboy Slim, a.k.a. Norman Cook, looks like, his portrait adorns a wall 2 min. 24 sec. into the clip. What elevates the video above mere novelty are the small touches Walken eyeing up some laundry, ringing a bell, slipping on the elevator. If they handed out Oscars for music-video performances, Walken would have been a dead cert. He could also claim an assist in the direction, as he helped choreograph the dance.
