Unclear whether sequence took place in Maldives or Australia; according to the Guardian "Silverback, which is part of All3Media, hired a young Australian, Alex Vail, to film the manta rays off Australia. He spent 16 weeks awaiting their arrival.", but all of the BTS captions on Instagram refer to the Maldives
