36 Hours is a 1965 German-American war suspense film, based on the 1944 short story "Beware of the Dog" by Roald Dahl. The picture stars James Garner, Eva Marie Saint, and Rod Taylor and was directed by George Seaton. On June 2, 1944, a German army doctor tries to obtain vital information from an American military intelligence officer by convincing him that it is 1950 and World War II is long over. Plot Having attended General Eisenhower's final briefing on the upcoming Normandy landings, U.S. Army Major Jeff Pike is sent to Lisbon, Portugal on June 1, 1944, to meet an informant to confirm that the Nazis still expect the invasion at the Pas de Calais.
