Frankenheimer refused to film the gunfights in slow motion, believing onscreen violence should be depicted in real time. Mick Gould, the film's technical advisor and a former instructor in the advanced training wings of the Special Air Service, trained the cast in weapons-handling and guerilla military tactics. The physical stunts were coordinated by Joe Dunne.
