The protagonist says:
What do you think spies are? Moral philosophers who measure everything under the will of God or Karl Marx? They are not. They are just a bunch of seedy squalid bastards like me. Little men- queers, drunkards, henpecked husbands, civil servants- playing cowboys to brighten their rotten little lives. Do you think they sit like monks in London balancing good and evil?
This is easily the best spy movie I have ever seen.
Intelligent. Intricately woven. Honest. Cynical.
James Bond turns out to be just another action hero with the job tag of a ‘spy’ to cook up some reason to show many foreign locales. If you really want to see how spies operate, this is one of the movies that you should see.
