iPhone, knowledge, skill, another half million in fancy equipment, and you are good to go!
Seriously though, there was an astounding amount of cool gear in the behind the scenes. If it was just a guy shooting handheld iPhone using his skill and knowledge, that's one thing. It seems to be a different value proposition to take all the equipment, and crew, from a multi million dollar production company, and just swap the camera for an iPhone. It is extremely impressive quality demonstration, but not clearly accessible to the typical iPhone purchaser.
