By the mid-1960s the screen was awash with spies so other than trying to invent a new hero in the Matt Helm/Derek Flint vein or revamping older characters such as Bulldog Drummond or sending up the entire genre in the style of Casino Royale (1967), it was difficult to find a fresh angle.
Assignment K does in some measure succeed, in part by going down the grimy route of The Spy Who Came in from the Cold (1965), in part by stuffing the picture full of glorious scenery – the Austrian Alps – and in part by turning Stephen Boyd into the kind of spy who has begun to question the entire business. For reasons unspecified, former racing driver turned toy salesman Boyd is running his own spy operation loosely linked into British intelligence but when the network is compromised his life and that of new love interest Camilla Sparv is endangered. Things get trickier when she is kidnapped and he has to save her while not compromising his own agents.
There is enough mystery to keep the plot, uncoiling like Russian dolls, ticking along and the entire effort is underwritten by some decent tradecraft, dead letter drops, microfilm hidden inside cigarette filters and so on. tension is surprisingly high. And Boyd is surprisingly human, falling properly in love for one thing, not just treating women in the James Bond/Matt Helm fashion as notches on a bedpost, not ice-cool under pressure either, face knotting in fury on occasion, and not so accomplished in the old fisticuffs department.
Michael Redgrave, Leo McKern and a pre-Please, Sir John Alderton provide decent support though Jeremy Kemp is somewhat subdued. But Boyd is a revelation, given a lot more to do than stick out his chin and growl. Here, his screen charm and charisma is at its best and while he was never going to attract the attention of the Oscar fraternity is entirely believable as a spy coming to wonder at decisions taken.
Sparv, too, is much better than I have ever seen her. Unlike her turn in Murderers Row (1966), her role is not merely decorative and the unfolding romance would work perfectly well just as a love story never mind tucked away in the guise of a spy thriller. There is a lovely demonstration of her acting skill, although an odd one to describe, as she pulls on a bathrobe and shimmies out of the towel underneath; I can’t believe that was ever scripted, but if you watch it you will see what I mean.
Director Val Guest was usually labelled a “journeyman” despite a repertoire that included The Quatermass Xperiment (1955) and its sequel, Yesterday’s Enemy (1959) and sci-fi The Day the Earth Caught Fire (1961) and he had previous form in this genre with Where the Spies Are (1966) which played more to the comedy gallery and did some work on Casino Royale to boot. His work here falls into the efficient category, but it does zip along at the same time as allowing Boyd and Sparv to develop their characters and make their relationship believable. All in all quite enjoyable.
