 The name Illya Kuryakin comes from a Broadway play written and  directed by Jules Dassin. "Ilya Darling" is Dassins musical  adaptation of his earlier film "Never on Sunday," or in Greek "Pote  tin Kyriaki". The irony lies in the fact that the Kuryakin character  is Russian and Dassin was blacklisted for years as a suspected  Communist.
