Robert Klein (Alain Delon) is a man mostly untroubled by moral qualms: he buys art, and if he manages to get a particularly good deal because one of his clients desperately needs money to escape Nazi-occupied France well— all's fair in business. When a mistake with some papers leads to him being confused with a different (and Jewish) Monsieur Klein, Robert's faith in the French bureaucratic system reassures him that the matter will be dealt with promptly. As the regime grows more openly hostile and his situation grows more dire, Klein embarks on a desperate chase to find his double and prove who he really is.

Director Joseph Losey was a man of some experience with being hunted, having fled Hollywood in the 1950s after a subpoena from the House of Un-American Activities Committee to explain his communist sympathies. His later works (including the 1971 Palme d'Or Winner The Go-Between) frequently explored the ambiguity of identity and the stifling class structure of his adopted UK home, but for this production he worked with Franco Solinas (co-writer of The Battle of Algiers) to create something at once deeply introspective and highly political in its depiction of Vichy France. Losey's surreal, mirror-filled nightmare world and a wonderfully chilly palette by cinematographer Gerry Fisher are served well by this stunning new 4k restoration of Mr Klein.
