This is one of top Cold War spy movies of all time, if not THE top one !Everything clicks in this movie, and Richard Burton is at his best. Lots of suspense, it will keep you interested the whole time on screen. Actually Burton is very sexy in this movie, you can see what Elizabeth Taylor saw in him as a man and as a lover !
Richard Burton stars as a burnt-out British agent at the height of the Cold War. He's old and tired, but most of all, he's a drunk. He's convinced (ordered) to take on one more dangerous under cover mission that may cost him his sanity and his life. This is well made and intense from beginning to end. For those that aren't familiar with the work of Richard Burton, watch this film. It's easy to see why he was one of the greatest actors of his time.
