It was probably never going to work. I can’t imagine there’s much nostalgia for the show. It was too long ago, and there really isn’t that much to hang a franchise off. If you want to make something that looks like a dated Bond clone (or a homage-like retro Bond clone), you don’t really need to hitch your star to a barely remembered TV series.
Truth be told I actually do have fond memories of the show. I thought Robert Vaughn and especially David McCallum were totally cool when I watched repeats of the show on the telly way back when, and I thought they worked well together. I bought their friendship / partnership even before I really understood why an American and a Soviet spy should really have hated each other.
I always assumed they liked each other and worked well together because they were too cool for ideological / patriotic bullshit.
I still assume cool people like each other because they’re too cool for ideological bullshit. It’s the way to live, as far as I can tell.
It’s not really fair to call it a Bond clone, since Ian Fleming himself was involved with the show, and had basically conceived of it as being some kind of American Bond tv show (with Napoleon Solo as the main character). They threw in a cool blond Russian looking guy, and that was history being made.
