McClory and Whittingham then sued Fleming, which led to a settlement in 1963 that gave McClory the film rights to the novel. During the lawsuit, Whittingham stepped down as 'co-plaintiff' and stood by McClory as 'principal witness', having previously signed away all his rights "of whatsoever nature" entirely when the screenplay was presumed finished. As a result of the settlement, future versions of the novel were forced to credit, "based on the screen treatment by Kevin McClory, Jack Whittingham, and Ian Fleming" (in that order). Two adaptations of "Thunderball" were subsequently made, the first being "Thunderball" in 1965 as part of the series of films from Eon Productions. The second adaptation was the film "Never Say Never Again" in 1983. Further adaptations had been planned at one point or another by McClory, but were scrapped due to lawsuits from MGM and United Artists.
