Never Say Never Again is a 1983 spy film directed by Irvin Kershner. The film is based on the 1961 James Bond novel Thunderball by Ian Fleming, which in turn was based on an original story by Kevin McClory, Jack Whittingham, and Fleming. The novel had been previously adapted as the 1965 film of the same name. Never Say Never Again is the second and most recent James Bond film not to be produced by Eon Productions, the usual producer of the Bond series, but by Jack Schwartzman's Taliafilm, and was distributed by Warner Bros. instead of United Artists. The film was executive produced by Kevin McClory, one of the original writers of the Thunderball storyline. McClory had retained the filming rights of the novel following a long legal battle dating from the 1960s.
