Mervyn Ian Guy Hamilton (16 September 1922 – 20 April 2016) was an English film director. He directed 22 films from the 1950s to the 1980s, including four James Bond films.

Hamilton directed his first James Bond film, Goldfinger (1964). He returned to the Bond film franchise with the chase- and heavily gadget-dependent Diamonds Are Forever (1971), Live and Let Die (1973) and The Man with the Golden Gun (1974). He claimed in a much later interview that he had instructed Roger Moore not to mimic Sean Connery's rendition of James Bond.

Diamonds Are Forever is a 1971 James Bond spy film and the seventh in the James Bond series produced by Eon Productions. It is the sixth and final Eon film to star Sean Connery, who returned to the role as the fictional MI6 agent James Bond, for the first time since You Only Live Twice (1967), having declined to reprise the role in On Her Majesty's Secret Service (1969).
