was loosely based on Joseph Conrad's novel, The Secret Agent (1907), about a woman who discovers that her husband is a terrorist, and Secret Agent, based on two stories in Ashenden: Or the British Agent (1928) by W. Somerset Maugham. At this time, Hitchcock also became notorious for pranks against the cast and crew. These jokes ranged from simple and innocent to crazy and maniacal. For instance, he hosted a dinner party where he dyed all the food blue because he claimed there weren't enough blue foods.

The film saw Hitchcock receive the 1938 New York Film Critics Circle Award for Best Director.

However, producer David O. Selznick offered him a concrete proposal to make a film based on the sinking of , which was eventually shelved, but Selznick persuaded Hitchcock to come to Hollywood. In July 1938, Hitchcock flew to New York, and found that he was already a celebrity; he was featured in magazines and gave interviews to
