I recently worked on a Lipton Ice Tea commercial. I was a prop buyer for it. This involved a week of prop sourcing books, lampshades, cushions, magazines, record covers and working closely with special effects company 'machine shop'.
It was shot at under water studios in Basildon. All props had to be individually dropped in and put in place by the scuba diving art team, making sure everything was weighted down, filling props with weights.
Never experienced an under water shoot before, it was very time consuming! Was amazed how long the models could stay under water.
Looking forward to seeing the finished piece!
