The Passionate Stranger (U.S. A Novel Affair) is a 1957 British drama film, directed by Muriel Box and starring Margaret Leighton and Ralph Richardson. It uses the film within a film device, with the "real" part of the plot shot in black-and-white and the "fictional" element in colour. The interior scenes were shot at Shepperton Studios, with location filming taking place at Chilworth, Surrey. Box stated that the film was intended "to debunk the sentimental novel...a mild satire on romance as opposed to reality, and the unhappy consequences of confusing the two".
