I Spy

A look at British spy stories, ranging from classic Hitchcock films of the 1930s to eighties paranoia in Defence Of The Realm, a mixture of the commonplace with the extraordinary - the ease with which laughs turn into thrills, the way a coded secret can suddenly mean life or death for a group of innocent people. Featured stars include Robert Donat, Kenneth More, Deborah Kerr and Margaret Lockwood in films such as Sabotage, The Lady Vanishes (1938 and 1979) and The 39 Steps (1935, 1959 and 1978).
