Losey's early Hollywood work included The Dividing Line and The Boy With Green Hair and Mr Klein contains elements of both inasmuch as he is still saying that if you're 'different' you'll wind up paying the price. He seems to have taken a leaf out of Jean-Pierre Melville's book and shot the film in muted, autumnal color which lends an ironic touch of austerity to the story of a man who deals in fine Art and lives a sumptuous lifestyle. Other posters have dealt both with the plot and its Kafkaesque overtones so it would be superfluous to repeat that here. Like the majority I found it an excellent effort and for a French film buff like me the pleasure was enhanced by a glimpse of Gerard Jugnot, a great cameo by Louis Seigner, a telling appearance by Michel Aumont, an all-too brief couple of appearances by the wonderful Suzanne Flon and Michael Lonsdale in fine form as Klein's lawyer. The Biter Bit element MAY be a tad obvious and overdone, true, but Delon's central performance plus the contributions already mentioned help take the edge of this whilst the startlingly effective opening of a naked woman submitting to an examination in order to prove her non-Jewishness is somewhat wasted by not being effectively linked to the main story but these are minor quibbles from one who has always found Losey somewhat overrated but who thoroughly enjoyed this late offering.
