Wednesday Matinee: The Clouded Yellow (1950) – Jean Simmons, Trevor Howard, Barry Jones, Kenneth More

The Clouded Yellow is a 1950 British mystery film directed by Ralph Thomas.
After leaving the British Secret Service, David Somers (Trevor Howard) finds work cataloging butterflies at the country house of Nicholas and Jess Fenton. (The “clouded yellow” of the title is a rare species of butterfly.) After the murder of a local gamekeeper, suspicion wrongly falls on their niece, Sophie Malraux (Jean Simmons).

Somers helps Sophie to escape arrest and they go on the run together, Somers using his secret-service skills and contacts to evade the police. After a cross-country chase they arrive at Liverpool with the intention of leaving the country by ship.
