The Deadly Affair - 1966 adaptation of a John Le Carre novel (Call For The Dead, and with the name of the George Smiley character changed to Charles Dobbs due to a rights issue). On the face of it, it seems an unremarkable, run-of-the-mill typical sixties spy drama, with infidelity, intrigue, lots of intense conversations in drawing rooms etc.
But being a Sidney Lumet film, there is of course more to it than that. Lumet insisted on not showing the touristy side of London, and de-saturating the colour to give it a very drab but interesting look. He also used a lot of hand held camera in real locations, which really helped to give an impression of sixties London as it was, and not how it was often unrealistically portrayed.
The other plus point is the concentration on secondary characters, notably Harry Andrews stoic, and sometimes brutal Inspector Mendel, Roy Kinnear in a straight role as a sleazy car salesman, and Simone Signoret in a very late career role and looking somewhat world weary, though still a very good actress, Maximillian Schell, Kenneth Haigh, A very young looking Lynn Redgrave and an unbilled David Warner (playing Edward II in an on-stage performance during a tense sequence in a theatre), and Corin Redgrave.
The portrayal of the seedier side of London is very well realized, especially in the sequence where Harry Andrews goes looking for Roy Kinnear in a pub, and beats him to a pulp. Quite uncharacteristic and brutal for the time, as was the general look of the movie with handheld cameras and the washed-out look.
A bit of a nostalgia trip I guess, but I can remember watching this on TV some 30 years back and it left an impression on me.
Well worth watching if you like Le Carre and sixties British spy drama's.
