Domino Derval (Claudine Auger) harpoons Emilio Largo (Adolfo Celi) as James Bond (Sean Connery) and Largo fight for control of the ship Disco Volante, getting revenge on Largo for the death of her brother. The Volante crashes onto the rocks and explodes. This film is littered with dead bodies such as MI6 agent Paula Caplan (Martine Beswick), SPECTRE assassin Fiona Volpe (Luciana Paluzzi), imperturbable Largo henchman Vargas (Philip Locke) and a plethora of divers as Bond and the CIA foil the plot to recover two atomic bombs from a downed Vulcan bomber sunken in the Caribbean.
Thanks, Evil Ed!

This movie has the same source novel as Never Say Never Again. You can't exactly call it a remake, because due to some complicated licensing agreements (and several lawsuits), two different groups both got the rights to adapt the Thunderball novel, and these are the results.
