S.P.E.C.T.R.E. has hatched its latest mission under the leadership of criminal mastermind Emile Largo: hijack NATO nuclear warheads and launch devices while holding a major British/U.S. city ransom for a large sum. Now Agent 007 is dispatched to Nassau to rendezvous with the sexy sister of a murdered NATO pilot and do reconnaissance work into Largo's suspected illicit affairs. "Thunderball" is a mumbled, silly, but not entirely without enjoyment Bond installment. It features forgettable villains as well as sexy but equally unmemorable Bond girls, yet Sean Connery remains his usual, affable self. The story is uninspired and poorly constructed which particularly rings true in the underwater denouement sequences which is confusing and anticlimactic. "Thunderball" marks the first film where the formula begins to wear thin.
