Apparently, this ad was directed by Steve Nash himself. According to an interview in The Arizona Republic, Nash says:
At first, the idea was to shoot on different mediums - camera phone, 8-millimeter, 16-millimeter (the eventual choice), security footage. My idea was the city was watching me. The genesis was a lot of people film me or take a picture of me in the city on cellphones. If it’s such an appetite to see me do normal things, it was an idea to do something people like.
I think he did a good job. The ad is raw, gritty, and real: a bit like Nash himself.
