Directed by Fritz Lang & starring Gary Cooper & Lili Palmer this rare film mixes intrigue with the atomic threat tension builds as a research scientist turned spy (Cooper) has to enter an occupied Europe of World War 2. Cooper is backed up by a host of talent including Robert Alda (father of Alan Alda of M.A.S.H. fame). The film culminates in a vicious h&-to hand duel with & Italian Gestapo agent (Marc Lawrence). This film has an intrigue all it's own & is unique in many ways. The thread holding it all together is the down home character played credibly by Gary Cooper as the simple man thrust into a complex situation.
