The spy film, also known as the spy thriller, is a genre of film that deals with the subject of fictional espionage, either in a realistic way or as a basis for fantasy. Many novels in the spy fiction genre have been adapted as films, including works by John Buchan, le Carré, Ian Fleming (Bond) and Len Deighton. It is a significant aspect of British cinema, with leading British directors such as Alfred Hitchcock and Carol Reed making notable contributions and many films set in the British Secret Service.
