Danger Within (U.S. title: Breakout) is a 1959 British war film directed by Don Chaffey and starring Richard Todd and Bernard Lee. It was written by Bryan Forbes and Frank Harvey, based on the 1952 novel Death in Captivity by Michael Gilbert, who had been a prisoner of war held by the Italians at PG 49 in Fontanellato. A combination of POW escape drama and whodunit, the film set in a prisoner of war camp in Northern Italy during the summer of 1943.
