An excellent Le Carre adaptation, though one which differs from the book somewhat. The Department is a fading section of British Intelligence desperate to recapture former glories. When they find out about apparent Russian missiles in East Germany they see the chance to regain their standing by sending a man in to verify the information...
Polish layabout Leiser (Christopher Jones) is whom LeClerc (Ralph Richardson) and Avery (Anthony Hopkins) find to infiltrate the Iron Curtain. Leiser doesn't care about politics, he just wants to live in the West and chase girls. However he is trained to be a killer and some basic spycraft and then sent over. What could go wrong?
A lot in fact, from the start the operation is bungled and the East Germans are never far away from Leiser, who hooks up with local girl Anna (Pia Degermark) and travels across Germany in an old lorry leaving the odd body behind...
Dark and bleak but also having a touch of "Swinging London". Leiser is a bit of a blank slate, his motivation is rather vague, his characterisation a bit undeveloped. The film looks beautiful though and has a cynical edge to the glamour and sunshine.
