This original film version of the mystery classic became one of Alfred Hitchcock's early triumphs, spinning the suspenseful yarn of a vacationing Canadian man (Robert Donat) accused of murder. Pursued by both the police and enemy spies at the same time, he attempts to unravel the dangerous enigma of "the 39 steps," with humorous and hair-raising predicaments befalling him at every turn. With Madeleine Carroll, Godfrey Tearle, and Peggy Ashcroft. 86 min.
