At the end of the scene on screen, Bond pulls himself out of the pool closely pursued by a shark. Initial reports claimed a dead one was supposed to be used, pulled on a wire.
Special effects coordinator John Stears later revealed the shark was unexpectedly still alive and began to thrash. Sharks will attack an injured one and horrifying a feeding frenzy erupted, as Stears screamed, “Get me out of here.”
Sharks plagued the entire film shoot, with all the main underwater scenes at sea having to be shot at very low tide, due to the number of wild sharks in the area.
Back safely on dry land, Connery was much more playful, and Thunderball Bond Girl Martine Beswick, who plays agent Paula, recounted one hilarious moment.
