HE MOVED LIKE A CAT, FOR A BIG MAN, MOST UNUSUAL. THE ONLY OTHER ACTOR WHO MOVED LIKE THAT WAS ALBERT FINNEY

Cabby Broccoli. paraphrase

Very insightful remark.

I would just note, as an aside, that they had wanted McGoohan, for good reasons, who had turned them down. I think he would have been Fleming's choice. But for certain aspects of Bond, he was wrong, and saw it. 

Le Carre puts some aspects of this issue very well. 

McGoohan, personally, rebelled against the kind of role Fleming had created, when he turned fron Danger Man, Secret Agent, to do The Prisoner.
