Trivia, insights & behind the scenes
The 'Thunderball' script was legally disputed for years — Ian Fleming had co-written a screenplay that became the novel, then had to settle out of court to make this film.
This is the highest-grossing Bond of the '60s, and basically invented the underwater action sequence that 'Avatar 2' is still paying homage to.
