If spies are allowed, I am vacillating between #6 from The Prisoner and Flint from In Like Flint. Both had extraordinary self-presence, which showed in the very way they walked. Flint's misogyny is a problem, but his self-assurance and physical co-ordination might beat #6's. #6 was also extra stoic, and was always even handed with women and went to the limit to help those who needed it.
I think #6 had more of a real influence on my real life (still take cues from his version of holiday-wear in clothing), but come to think of it he's TV, not movies. So, I'll go with Flint, but not the pointy shoes--I'll keep #6's deck shoes.
Correction, please: To lean toward contortionist is duplication of effort. Most comical.
