Love is like a butterfly, as soft and gentle as a sigh.

The Clouded Yellow is directed by Ralph Thomas and written by Eric Ambler and Janet Green. It stars Trevor Howard, Jean Simmons, Sonia Dresdel, Barry Jones, Kenneth More and Geoffrey Keen.

Taut British spy thriller with Hitchcockian flavours, The Clouded Yellow finds David Somers (Howard) as an ex-secret service operative working as a butterfly cataloguer who finds himself neck deep in a murder plot. Set in the North of England, with some good locations to be spotted by the keen of English eye, the story revolves around the murderous goings on at the stately home where Somers now works. With Sophie Mairaux (Simmons) the chief suspect, Somers comes to believe she is innocent and sets about proving so.

It follows a reliable formula, where the set-up introduces the main players, the hero in waiting takes it upon himself to use his skills to prove he’s right, which builds to an odd couple on the lam final quarter of film. The strength is in the characterisations, particularly Somers with his past hanging heavy on his mind, and Mairaux and her current predicaments which involve her being surrounded by vile people. Thomas directs assuredly, mixing the drama with humour and affection, and the suspense and mystery elements are maintained up until the dramatic conclusion. Cast are suitably in good tune with the material, with Howard and Simmons making a compelling and complex coupling. 7/10
