The whole show (715 minutes) was shot as it supposed to be an one shot. There were several changes of camera and gear but most of them were cleverly hidden (for example by bypassing people in front of the camera). So technically it's the longest one shot of all time.
Due to strict health restrictions on set, every crew member was tested for Covid-19 before and then the whole crew was put in quarantine on the island until the event was streamed.
