 The helicopter chase was filmed with a radio controlled miniature helicopter.The sounds of the boat chase were replaced in post-production since the boats were not loud enough, and the explosion, shot in Pinewood, got out of control, burning Walter Gotell's eyelids and seriously injuring three stuntmen.Photographer David Hurn was commissioned by the producers of the James Bond films to shoot a series of stills with Sean Connery and the actresses of the film.
