I have been eagerly awaiting this production for a long time and have not been disappointed. Never have I seen such a compilation of such fabulous performances together. No way is this another James Bond, it is how the world of espionage was, and is today. No car chases in Aston Martins or gadgets but a world of seedy little offices and the grim reality of this genre. What had the greatest impact on myself was the slow deep menace conveyed by all. Difficult to single out any one performance as all were amazing but I particularly admired Gary Oldman, Mark Strong and Tom Hardy for their work. At times this film has some unexpected moments of shocking cruelty. Complex character portrayal is presented in a slow deep style that only inspires you to know more about the person. The story itself is a classic and known by many, yet this production introduces a few changes which work well. One of the most absorbing and classy movies I have seen and has left a lasting impact on me. Please, please, please, make Smiley's People now.
