THE 39 STEPS

UKTV PLAY THRILLER

John Buchan’s classic 1915 novel about spies, military secrets and an innocent man on the run with a woman after being accused of murder has been adapted many times, notably in the 1935 Hitchcock version with Robert Donat. Spooks’ Rupert Penry-Jones (above) stars in this 2008 BBC film, which is less like the book, with more of a romantic subplot and a climactic scene involving a submarine.
