Codice 3: emergenza assoluta

Joseph Barbera, of Hanna-Barbera cartoons fame, had an idea to make a movie about ambulance driving. Twentieth Century Fox gave him development money to deliver a script. Barbera heard that screenwriter Tom Mankiewicz, who'd written several James Bond movies, was interested, and hired him. Barbera set up Mankiewicz with a local ambulance company for some "real world" experience. Mankiewicz rode in an ambulance driven by Tom "Hap" Hazard, and witnessed the results of a stabbing on the Sunset Strip, as well as potential suicide and heart attack victims. After these ride-alongs, Mankiewicz know he had the makings of a terrific movie, and wrote the original script for this movie.

At several places in the film, the actor's lip movements do not match the audio, revealing that the dialogue was toned down. During Tony's job interview, Fishbein is heard saying "all-day heat on" but his lip movements are "hard-on." Later, when discussing Murdoch, Jugs is heard saying "a $100 bill sticking out of his ear" but her lips clearly say "out of his ass."
