Roger Moore, 1972-1985
Roger Moore had to work around eccentric Sean Connery's involvement in the Bond films' titular role. Moore was featured in seven films, starting with Live and Let Die and ending with A View to Kill. Moore was the first English actor to take on the role.
George Lazenby - 1969
Only one film was made with George Lazenby. He was an interim-Bond after Sean Connery quit and before Roger Moore was hired. The only film Lazenby starred in was On Her Majesty's Secret Service. He was even nominated for a Golden Globe.
