^McLachlan's Agent Cooper in Twin Peaks always seemed inspired by Solo to me.
Hmm, I can't really see that. As I remember Cooper, the main quality I'd ascribe to him is that he was earnest
. He was quirky, but very earnest and sincere and a total Boy Scout. Napoleon Solo was rarely earnest. Vaughn went through the whole series with a wry, impish attitude of being in on the joke and above it all, as though he were just making a game of everything. And he was anything but a Boy Scout; he was as much a womanizer and killer as James Bond, but much more playful and carefree about it than any incarnation of Bond save Roger Moore.
