Whilst i respect those reviewers who have read the original book, and therefore can meaningfully talk about the adaptation's faithfulness, I can only review this audio adaptation as a piece of stand-alone radio drama, with no idea of how accurate the mood or characterisations are.
As a dark, bleak drama set in the period of the Cold War, it is infinitely more compelling than the utterly unreal seeming James Bond version of espionage.
Production values are great, there is brilliant use of sound effects and music to set scenes and indicate the passage of time and place.
Brian Cox as Alex Leamas, the world-weary, bruised and complex intelligence officer and Ruth Gemmell as Liz, the young British CP member and Leamas' girlfriend are both superb. Cox particularly holds the whole piece together.
Like another reviewer however, I'm a little surprised that the wonderful Simon Russell Beale, as Smiley, received star billing. Maybe Smiley has a more central role in the other le Carre radio adaptations, but in The Spy Who Came In from the Cold he occupies about 2 minutes of 3 hours air time. So I'm also a little surprised at reviews which single him out for praise! as you have to listen very very hard to identify he has appeared in a scene or 3! He's talked ABOUT all the time, but isn't really in the action of this one at all!!! The real star is Cox; without his weighty performance this could garner no real accolades.
I couldn't go the whole 5 stars as there are some pretty wincing attempts as German accents, with the accent playing the actors, rather than the actors playing the characters.
Afraid without Cox I'd have had to stop listening once the action shifted to Berlin, as the cod accents had me gritting my teeth and wincing!!!
Cox, Gemmell, a classy script, excellent music and the fine skills of the producer/director and recording engineers make this a tight and absorbing piece
