As a matter of record, there were hundreds of soldiers who returned to the States with little memory of what their role was in World War Two. Here in this story called " 36 Hours " an Intelligent's Officer (James Garner) Major Jefferson F. Pike is given the latest secret plans for the Invasion of Normandy and is thereafter sent to Lisbon Portugal to ascertain if the German High Command are chasing the false ruses put out by the Allies. What the U.S Intelligence office does not know is, the Major is unexpectedly kidnapped and sent to Germany to undergo a daring experimental scheme. The Germans' have a highly educated Phychiatrist, Major Walter Gerber (Rod Taylor) who is going to try and convince the Major, that not only is World War II is over, but it is now six years in the future. With the help of Anna Hedler (Eva Marie Saint) heading a highly trained staff of English speaking Germans and a secret, isolated military compound they hope to trick him into revealing the Allies invasion plans. All things go according to plan until the one thing they had hoped would not happen does. Although Garner proves to command the screen with his role, it is Taylor who elicits sympathy for his compassionate character and we discover ourselves rooting for Gerber to succeed. A dramatic film and one which allows the audience to wait impatiently for the hours to be extended. ****
