THE MEN FROM U.N.C.L.E.
Ironically this kitsch example of 60’s espionage was recently given the big screen treatment, much like The Avengers was in the 1990’s (though we try not to talk about that), and from Vaughn’s mentor & alumni Guy Ritchie no less. The connections again are clear: suave American agent Napoleon Solo on international missions stopping world-destroying plots with his Russian partner, but in truth the inspiration lies more with how U.N.C.L.E operates as part of the UN, and independent organisation outside of specific governmental, bureaucratic oversight, which to a degree is how Kingsman seems to work.
Though The Man from U.N.C.L.E isn’t perhaps as heavy a touchstone for Vaughn as some of these other examples, there’s no doubt it factors in, and the period stylistics of Ritchie’s damn good recent update prove their films, and the show that inspired it, share more than a little DNA.
