He put unshakable credibility and strength in the persona he projected into every character.
He didnt pump out multiple junk themes like some , I dont think it possible to identify who the best actor in history was but Brando , McQueen , Newman , Nicholson , Peter OToole , Daniel Day-Lewis , Denzel Washington ,Morgan Freeman , De Niro , Harrison Ford , James Cagney , Charlie Chaplin , Humphrey Bogart , Cary Grant , Laurence Olivier , Sydney Poitier , Kirk Douglas , James Earl Jones , Jack Palance all up there too in their own way.
All Subject to personal interpretation.
Hats off to Connery . Faultless authenticity really
