Felix Leiter is a fictional character invented by Ian Fleming in the James Bond books, who also appears in the Bond movies. In the films, Leiter works for the CIA, and assists Bond in his various adventures. He was portrayed by Jack Lord in the 1962 film Dr. No.
In the film, Felix meets James Bond when he is fighting Quarrel and breaks up the fight. Quarrel, who is Felix's agent, helps Bond reach Dr. Julius No's island. After defeating Dr. No inside his lair, Felix tows Bond and Honey Ryder from the island by boat.
Jack Lord was the first Felix Leiter, appointed into the role for the first Bond film, Dr. No. Eon Productions started filming the series out of the order written by Fleming (Fleming had started with Casino Royale, with Dr. No being the sixth novel). Leiter was not present in the Fleming novel, but the writers added the character to the film. Bond scholars Smith and Lavington consider Leiter to offer negligible help to Bond, largely because there is no role for him in the novel, a point with which continuation Bond author Raymond Benson agrees, noting that he is "extraneous to the dramatic action". Jeremy Black agrees, although points out that the inclusion of Leiter was a sign of American influence in the Caribbean.
When the role of Leiter was brought back for the third Bond film, Goldfinger, in 1964, Lord was again approached to play Leiter; according to screenwriter Richard Maibaum, Lord demanded co-star billing with Sean Connery, a bigger role and more money to reprise the role. The producers instead decided to recast the role
Lord played Leiter in a "swaggering" fashion, according to Smith and Lavington, and they considered him "excellent, an effective American version of James Bond." Bond scholars Pfeiffer and Worrall agree, stating that Lord's was "one of the most satisfying portrayals of Leiter".
