The set-up for this shot was performed by the 3 scuba divers. They clamped together the 10′ walls on the 12′ x 15′, wheeled platform in the shallow-end.  The set was then slowly rolled down to the deep-end.  Mark Zibert swam down to get the shot . . . the model deserves a Nobel Prize.  Peter D’ellAgnese of Lucky Boy Productions was the calm and amazing producer.
