I just watched (for the umpteenth time) David Greene's The Strange Affair (1968). I must admit to having a soft spot for obscure British movies from the 50s - 70s.
Michael York stars as Peter Strange, a young and inexperienced new police constable who gets star place in a set of uncompromising photographs when he gets picked up by an under age and very groovy Susan George, who plays a hippy. Things go from bad to worse, and soon he's implicated in a major corruption charge by the very dodgy Jeremy Kemp.
Never released on video or DVD anywhere, my copy came from a Brazilian TV station. It's a Paramount title so I wouldn't hold your breath waiting for a DVD release of this any time soon.
