Remember when commercials were big-budget enterprises, when Travel Depts (remember Travel Depts?) booked you First Class to LA or Bali or even the North Pole? (OK, that spot was for Coke, which I never worked on, and before my time. But still, I MIGHT have been sent there if I'd ever written polar bears into a script...) Anyhooooo. Enter fee-based compensations, risk-reward structures and procurement teams and what do you get? Crowdsourced commercials, the bane of agency confrontations with cash-strapped product managers. But clever minds at Mullen figured out how to make this all-too-frequent request work for them: don't leave creative up to the crowd. Curate the pics before you source them. Storyboard the spot. Direct the shots. Don't give up creative control. Starting today, the Airbnb twitter feed put out a call for wanna-be filmmakers to contribute their 6 second Vine to a brand film. The prompts are shot lists, well-thought out and very specific, such as a paper airplane flies thru diverse landscapes, left to right. Show the best parts of where you live! Mullen will choose and edit selects, then premier final montage online and on the Sundance Channel. All you need to enter is a piece of paper and camera phone. So much for gaffers and props masters as indisputable line items.
