American actor Yaphet Kotto joined the Bond series in 1973, playing politician Dr. Kananga and big time gangster Mr. Big in Live and Let Die. Dr. Kananga was a calm Prime Minister of San Monique, an island used to grow drugs that were to be smuggled into America. He would don a rubber face mask to become his alter ego Mr. Big, the ruthless gangster who controls most of Harlem.
He played the two characters well, and brought a unique contribution to the series. Kananga, alongside his taro reading mistress Solitaire, remains a popular and well known villain amongst fans. His death by a co2 filled bullet was a little cheesy though.
