After George Lazenby left the series, producers Harry Saltzman and Albert R. Broccoli tested other actors, but studio United Artists wanted Sean Connery back, paying a then-record $1.25 million salary for him to return. The producers wereinspired by Goldfinger; as with that film, Guy Hamilton was hired to direct, and Shirley Bassey performed vocals on the title theme song. Locations included Las Vegas, California, and Amsterdam. DiamondsAre Forever was a commercial success and received generally positive reviews initially. It was nominated for the Academy Award for Best Sound.
