'' La Grande Speranza '' ( '' The Big Hope '' ) , retitled '' Submarine Attack '' and '' Torpedo Zone '' in English , this low-key anti-war film is slow-moving and lacking in dramatic tension by action film standards , but conveys its message effectively . It is notable for being shot inside and on the deck of an actual submarine , and for winning both the Special Prize of the Senate of Berlin and the OCIC Award at the Berlin International Film Festival . Also noteworthy is the subsequent career of the only woman in the film , Lois Maxwell . One of the advisors on the film was Marcantonio Bragadin
