Creator of James Bond, Ian Fleming, modelled the fictional British Secret Service agent on himself and Hoagy Carmichael - an American composer, singer and actor who is referenced in two Bond movies.
Casino Royale: Vesper Lynd remarks "Bond reminds me rather of Hoagy Carmichael, but there is something cold and ruthless."
Moonraker: Branch Officer Gala Brand thinks that Bond is "certainly good-looking ... Rather like Hoagy Carmichael in a way. That black hair falling down over the right eyebrow. Much the same bones. But there was something a bit cruel in the mouth, and the eyes were cold."
