I was younger but to me it was the coolest show. In retrospect the show was a poor mans James Bond. It did have an amazing jazz soundtrack. Mr. Waverly was an extension of his character from North By Northwest. Vaughn was a leftist but McCallum is an anti socialist. One of the reasons he moved to America he said. Conversely Vaughn was an actual committed leftist and couldn’t stand living in America and moved to England.
Played by Leo G. Carroll who also played a wonderful Cosmo G. Topper.
I remember seeing Vaughn in a Grand Union in Ridgefield, CT in 1985.
What struck me is how short he looked. He was wearing blue jeans and leather jacket and a Stetson type hat.
He lived in Ridgefield at the time.
