20 Things You Didn’t Know About Thunderball (1965)
13. “Fine Way To Treat The CIA!”
Fittingly, Rik Van Nutter - who portrayed CIA agent, Felix Leiter in Thunderball - was married to Anita Ekberg from 1963 to 1975. Ekberg had not only starred in the first Eon Productions non-Bond film, Call Me Bwana (1963), but had also been featured on a billboard promoting it in From Russia With Love.
The filmmakers liked Van Nutter so much as a natural successor to Jack Lord's Felix Leiter from Dr. No (1962) that they contracted him to reprise the role in the next few Bond films. However, they could not find ways to fit the character into either You Only Live Twice or On Her Majesty’s Secret Service (1969).
By the time that Leiter returned in Diamonds Are Forever (1971), Van Nutter’s contract had expired and he was focusing on his and Ekberg's shipping business instead, which led to Norman Burton being (unpopularly) cast in the role instead.
Ironically, Van Nutter’s performance as Leiter in Thunderball was his best-remembered screen role.
