The 39 Steps is a 1959 British thriller film directed by Ralph Thomas and starring Kenneth More and Taina Elg. Produced by Betty Box, it is a remake of the 1935 Alfred Hitchcock film, loosely based on the 1915 novel The Thirty-Nine Steps by John Buchan.
In the film, diplomat Richard Hannay returns home to London, only to become inadvertently embroiled in the death of a British spy investigating the head of an organisation planning to sell the secret of a British ballistic missile. Hannay thus travels to Scotland to escape the police, and attempts to complete the spy’s work.
