George Robert Lazenby (; born 5 September 1939) is an Australian retired actor. Lazenby began his professional career as a model and had only acted in commercials when he was cast to replace the original Bond actor, Sean Connery, playing the character in On Her Majesty's Secret Service (1969). Since he appeared in only one film, Lazenby's tenure as Bond is the shortest among the actors in the series. He declined to return for subsequent Bond films and instead pursued other roles in Universal Soldier (1971), Who Saw Her Die?
