Thunderball

The fourth film in the Bond series finds the super spy (Sean Connery) battling a powerful organization named S.P.E.C.T.R.E. and its nefarious Number Two, Emilio Largo (Adolfo Celi), who has threatened to destroy Miami with an atomic weapon unless a huge ransom is paid. Of course, James Bond has something else in mind: a full-on infiltration of Largo's boat, the Disco Volante. With double the Bond girls (with Claudine Auger as the luscious Domino and Luciana Paluzzi as the villainous Fiona Volpe), this favored Bond outing features captivating underwater action sequences that hold up to this day.
