He was a man, take him for all in all,
I shall not look upon his like again.
(His first appearance with Peter Cushing–though their roles were relatively small, and they shared no scenes–was in Olivier’s Hamlet.)
Other reasons he was just plain cool:
He was a devoted and loyal friend. He spoke highly of his dear friends Peter Cushing and Vincent Price for years after their deaths, and was a mainstay for Peter when the poor man was a wreck over his wife’s death.
He spent over fifty years with his one and only wife. (He married a bit late–his early forties–but seemed to have gotten his wild-oat-sowing out of the way before that.)
Was related to Ian Fleming by marriage, and served with him in WWII. Fleming is said to have based Bond on three people: himself, Christopher…and Jon Pertwee.
Going on from that–he was in intelligence services during the war, and after his service with the RAF was part of a special force (nicknamed “The Ministry of Ungentlemanly Warfare”) whose purpose was, according to Churchill, to “set Europe ablaze.” Much of his work is STILL classified, so he never spoke in detail about it, but while filming Saruman’s death scene in LOTR he indicated to Peter Jackson that he knew very well the sound a man makes when stabbed in the back…
Was a trained singer, and an opera fan, but also dabbled in heavy metal–even releasing several metal songs. He said that headbanging in the car helped loosen up his neck muscles. (He did a studio recording of The King and I, as well, but I would have LOVED to hear him as Emile DeBecque in South Pacific.)
Was the Narrator on a studio cast recording of Rocky Horror.
Was, as some of you have mentioned, on Paul McCartney’s Band On The Run cover.
Was a fan of Warner Brothers cartoons (as was Peter Cushing) and used to make Peter laugh with a spot-on Yosemite Sam impression.
Was the only member of the LOTR cast to have met Tolkien personally.
Was quite conscientious about his fantasy roles–besides Saruman, he voiced King Haggard in the animated Last Unicorn. He took the book with him on set and discussed certain passages with the director that he felt HAD to be in there for the characters’ sake, and why.*
Played a good golf game, too.
*For a while, they were trying to get a new live-action adaptation off the ground, with Sir Christopher reprising Haggard once again. Efforts have once again picked up…but now we’ll never get to see Sir Christopher do the role again.
