After meeting a general, war correspondent Dick Ennis is assigned to accompany US Army Rangers for the upcoming attempt to outflank the tough enemy defenses. The amphibious landing is unopposed, but the bumbling American general, Jack Lesley, is too cautious, preferring to fortify his beachhead before advancing inland. Ennis and a Ranger drive in a jeep through the countryside, discovering there are few Germans between the beachhead and Rome, but his information is ignored. As a result, the German commander, Kesselring, has time to gather his forces and launch an effective counterattack. Ennis is with the Rangers who are ambushed at the Battle of Cisterna. From there, the film departs from being a view of all sides and levels of the campaign to a story of a handful of survivors making their way back through enemy lines. The men take shelter in a house occupied by three Italian women. A German patrol arrives at the house, only to be slaughtered by the Americans. Ennis asks what makes one human being willingly kill another. Corporal Jack Rabinoff replies that he loves it, and his lifestyle makes him live more than anyone else. Having almost reached friendly lines, most of the men, including Rabinoff, are killed in a shootout with a group of German snipers. It is during this shootout that Ennis is finally forced to kill one of the Germans with Rabinoff's gun. Only Ennis, Technical Sergeant Stimmler and Private Movie make it back and deliver intelligence about the German defense lines. The film ends with Ennis publicly questioning the competence of the Allied commanders and man's willingness to kill each other.
The film opened to mixed reviews in the US; many felt it did not work as well as Dmytryk's early war films. The New York Times film review was generally dismissive, and describes the film as "a very ordinary war movie with an epic title, produced by Dino De Laurentiis, the Italian producer... who thinks big but often produces small". In contrast, Chicago Sun-Times critic Roger Ebert had a more favourable opinion of the film, described it as "a good war movie and even an intelligent one".
Production
scored the film with a ballad called The World is Yours with lyrics by Doc Pomus that was sung beneath the credits by Jack Jones. Luigi Scaccianoce was the production designer. Peter Falk thought that the script he read was clichéd and wanted off the film. At the last minute, Dino De Laurentiis put Falk's name above the title billing and gave him his choice of writer for his character's dialogue. Falk stayed and wrote his lines himself. The production saw De Laurentiis bring infor the first time another actor who made a debut, Giancarlo Giannini, who would later do international films and would work with director Lina Wertmüller. Rabinoff is based on a real 1st Special Service Force soldier, Jake Wallenstein, who ran an illegal brothel of Italian prostitutes in a stolen ambulance. Wallenstein was killed by shrapnel at Port Cros during Operation Dragoon, the invasion of southern France.
