No real Spoilers, but seeing the film would help. While not nearly as good as "Guns of Navarone" or "Where Eagles Dare", this is still a very good flick. Why? Easy. Patrick McGoohan as "David Jones." He plays Jones just like he did John Drake of "Secret Agent" fame AND just like Number Six, the hero of "The Prisoner." My view of this film has always been that it's a story that sits chronologically between the two series. In fact, I like to look at it as Drake's last mission before he resigns and begins the Prisoner. With a little imagination and tongue in cheek, I'm sure you'll see my point. Jones talks like Drake and #6. In fact, at the end of "Zebra," Jones says "Do svidAniya," which can be taken as "Be Seeing You," the signature phrase of The Prisoner. He has the same amazing array of knowledge, like how to sink a sub, that the other two have. He is also very much a born survivor. A lesser actor would have died 4-5 times. McGoohan makes this film much more fun than it has any right to be. Without him, it would be very rough going for 2.5 hours until the rather flat ending. To those who are up to speed on "Secret Agent" and "The Prisoner", give this a look. You'll be very pleased to see an old friend at his best. McGoohan actually took time off from filming "The Prisoner" to make this and it shows. He was in Prisoner-mode the whole time, and for that I would recommend this film. RATING: 7 out of 10.
