The 39 Steps, 1935

A man(Robert Donat) comes to the aid of a young woman(Madeleine Carroll) only to get involved in a cloak and dagger chase through London and Scotland. The mysterious spy activities culminates in a novel climax. Donat and Carroll are flawless. Their banter will influence movie dialog for decades to come. This mystery is not that easily unwound.

A perfect example of the genius of Hitchcock's pre-war British period.
